3f3fd1a841 add SAIP template handling + v3.1 definitions
This adds classes for describing profile templates as well
as derived classes defining the profile templates of the
"Profile Interoperability Technical Specification", specifically
it's "ANNEX A (Normative): File Structure Templates Definition"

We need a machine-readable definition of those templates, so
we can fully interpret an unprotected profile package (UPP),
as the UPP usually only contains the increment/difference to
a given teplate.

SimAlliance/TCA "Interoperable Profiles" and apply personalization
operations on them.

5bbb144a31 Initial proof-of-concept SM-DP+ for GSMA consumer eSIM RSP
This commit introduces

* the osmo-smdpp.py program implementing the main procedures and the
  HTTP/REST based ES9+
* python modules for ES8+ and non-volatile RSP Session State storage
* the ASN.1 source files required to parse/encode RSP
* 3GPP test certificates from SGP.26
* an unsigned profile package (UPP) of a SAIP v2.3 TS48 test profile

As I couldn't get the 'Klein' tls support to work, the SM-DP+ code
currently does not support HTTPS/TLS but plan HTTP, so you either have
to modify your LPA to use HTTP instead of HTTPS, or put a TLS proxy in
front.

I have successfully installed an eSIM profile on a test eUICC that
contains certificate/key data within the test CI defined in GSMA SGP.26

242197b53d Add pySim.esim.bsp module implementing BSP (BPP Protection Protocol)
This is the protocol used for the ES8+ interface between SM-DP+ and the
eUICC in the GSMA eSIM system.
