c7c48718ba Get rid of [now] superfluous HexAdapter
With the introduction of using osmocom.construct.{Bytes,GreedyBytes}
in Change-Id I1c8df6350c68aa408ec96ff6cd1e405ceb1a4fbb we don't have a
need for wrapping each instance of Bytes or GreedyBytes into a
HexAdapter anymore.  The osmocom.construct.{Bytes,GreedyBytes} will
automatically perform the related hex-string-to-bytes conversion if
needed - and during printing we have osmocom.utils.JsonEncoder that
makes sure to convert any bytes type to a hex-string.

72186cce84 pySim.profile: Further refactor card <-> profile matching
The new architecture avoids sim/ruim/uicc specific methods in
pySim.profile and instead moves the profile-specific code into the
profile; it also solves everything within the class hierarchy, no need
for global methods.

5f2dfc28ff pySim/profile: Change match_with_profile from static to class method
This was suggested by vyanitskiy during gerrit patch review in
https://gerrit.osmocom.org/c/pysim/+/38049 in order to make the
upcoming eUICC CardProfiles simpler.

a3962b2076 Migrate over to using pyosmocom
We're creating a 'pyosmocom' pypi module which contains a number of core
Osmocom libraries / interfaces that are not specific to SIM card stuff
contained here.

The main modules moved in this initial step are pySim.tlv, pySim.utils
and pySim.construct. utils is split, not all of the contents is
unrelated to SIM Cards.  The other two are moved completely.

ce01f48b00 test_files: Test decoder also with ff-padded input
It's customary in the SIM card universe to right-pad data with ff bytes.
So far we only test decoders without such padding, which is unrealistic.
Let's also tests the decoders with extra 'ff' padding present.

For some files this doesn't make sense, so we add a _test_no_pad class
attribute that can be spcified to prevent this new "test with ff-padding"
from being executed for the test data of the class.

323a35043f Introduce concept of CardProfileAddon
We have a strict "one CardProfile per card" rule.  For a modern UICC
without legacy SIM support, that works great, as all applications
have AID and ADF and can hence be enumerated/detected that way.

However, in reality there are mostly UICC that have legacy SIM, GSM-R
or even CDMA support, all of which are not proper UICC applications
for historical reasons.

So instead of having hard-coded hacks in various places, let's introduce
the new concept of a CardProfileAddon.  Every profile can have any
number of those.  When building up the RuntimeState, we iterate over the
CardProfile addons, and probe which of those are actually on the card.
For those discovered, we add their files to the filesystem hierarchy.

f9e2df1296 cdma_ruim: Fix unit tests and actually enable them
As pySim.cdma_ruim was not imported by test_files.py, the unit tests
were apparently never executed and hence didn't pass.  Let's fix both
of those problems.

87dd020d5f Add very basic profile for R-UIM (CDMA) cards
R-UIM (CDMA) cards are pretty much like the normal GSM SIM cards and
"speak" the same 2G APDU protocol, except that they have their own file
hierarchy under MF(3f00)/DF.CDMA(7f25).  They also have DF.TELECOM(7f10)
and even DF.GSM(7f20) with a limited subset of active EFs.  The content
of DF.CDMA is specified in 3GPP2 C.S0023-D.

This patch adds a very limited card profile for R-UIM, including auto-
detecion and a few EF definitions under DF.CDMA.  This may be useful
for people willing to explore or backup their R-UIMs.  To me this was
useful for playing with an R-UIM card from Skylink [1] - a Russian
MNO, which provided 450 MHz CDMA coverage until 2016.
