So far we only implemented command encoding and response decoding.
Let's also add command decoding, which is useful for example when
decoding protocol traces.

This is a tool to work with eSIM profiles in SAIP format. It allows
to dump the contents, run constraint checkers as well as splitting
of the PE-Sequence into the individual PEs.

Our current implementation assumes that all COMPR_TLV_IE are created
with a raw tag value that has the comprehension bit set. Check for this
during the class __new__ method and print a warning if we have to fix it up

our implementation currently assumes that all derived classes are
created with a tag value that has the comprehension bit set.

The uppermost bit of COMPREHENSION-TLV tags indicates whether the
recipient is required to "comprehend" that IE or not. So every IE
actually has two tag values: one with and one without that bit set.
As all our existing TLV definitions of COMPR_TLV_IE have that bit set,
let's assume this is the default, but use the same definition also for
the situation where that bit is not set.

This method allows the caller to remove all NAAs of a certain type,

This tool can be used to test the SM-DP+. It implements the full dance
of all HTTPs API operations to get to the downloadProfile, and will
decrypt the BPP to the UPP, which is then subsequently stored as file on
disk.
Needless to say, this will only work if you have an eUICC certificate +
private key that is compatible with the CI of your SM-DP+.

Let's use the infrastructure of pySim.esim.http_json_api to define
the ES9+ API Functions. This can in turn be used by clients or even
osmo-smdpp can be ported over to using this infratructure rather than
open-coding a lot of the encoding/decoding of API request/response
parameters.

The "TCA Loader" is a freeware utility program published by the
Trusted Connectivity Alliance for testing SCP80, SCP81, SCP02 and SCP03
in UICCs. It can generate text log files of the APDUs it exchanges;
let's add this file format to pySim-trace

Now that CardKeyProvider is capable of storing key materials
transport-key-encrypted, we can use this functionality to look up the
SCP02 / SCP03 key material for a given security domain.
This patch implements this for the ISD-R and ECASD using a look-up by
EID inside the CSV.

It's generally a bad idea to keep [card specific] key material lying
around unencrypted in CSV files. The industry standard solution in the
GSMA is a so-called "transport key", which encrypts the key material.
Let's introduce support for this in the CardKeyProvider (and
specifically, the CardKeyProviderCSV) and allow the user to specify
transport key material as command line options to pySim-shell.
Different transport keys can be used for different key materials, so
allow specification of keys on a CSV-column base.
The higher-level goal is to allow the CSV file not only to store
the ADM keys (like now), but also global platform key material for
establishing SCP towards various security domains in a given card.

So far the main use case was to read a ProfileElement-SD from
a DER file. But when we want to construct one from scratch,
we need to have the constructor put some meaningful [default]
values into the class members.
Change-Id: I69e104f1d78165c12291317326dbab05977a1574
This way it's possible to programmatically inspect and modify the
high-level decoded key material inside a securityDomain profile element.

It's rather useful to have derived classes implementing specific
functions related to that SAIP profile type. Let's introruce that
concept and a first example for securityDomain, where methods allow
checking/adding/removing support for SCPs.

When de-MAC-ing at the recipient side, we must increment the cipher(!)
block number even if no ciphering is done at all.
We did this correctly for MAC (sender) case, but not on the de-MAC
(receiver) case.

In the eSIM RSP univers there are some rather ugly layering violatoins
where ASN.1 cannot be parsed but we have to mess with raw TLVs and the
details of DER encoding. Let's add two funtions that make it more
convenient to work with this: They return the raw tag as integer, or
even the entire encoded TLV rather than the value part only.

GlobalPlatform has a [non-public] "UICC Configuration" spec, which
defines some specific aspects of implementing GlobalPlatform in the
context of an UICC. Let's add some python definitions about it.

We used to re-encode those parts of a decoded ASN.1 struct that is
cryptographically signed in the GSMA SGP.22 specification. However, if
the received data follows a later spec and contains new/unknown records,
then our poor-man's attempt at re-encoding will render a different
binary, which in turn means the signature check will fail.
Let's instead do a manual step-by-step raw decode of the DER TLV
structure to extract the actual binary information of parts of ASN.1
objects.

Let's have the card tell us what the length is by indicating '00'
instead of stating 'FF'. This is better aligned with general practice
and won't break assumptions in other parts of the code like SCP
transport.

our utils.b2h() returns values in lower-case hex string notation,
so let's make sure the CardADF and CardApplication AID values are also
stored in lower case notation, othewise the matching baesd on AIDs
returned from the card will not work, specifically as we use uppercase
AIDs in pySim.euicc for CardApplicationECASD and CardApplicationISDR.
Rather than change those two instances, let's solve it in a generic way.
We already do the same for the CardFile.fid member.
