Robert Falkenberg b07a3e9c87 Add codecs for EF_SPN and GSM strings via construct
This will replace the hand-crafted codec for EF_SPN
by a struct definition using the construct library.
Old encoders are updated and kept for API compatibility
but are not used internally anymore.

New data structures:
* Rpad(Adapter): Right-padded bytestring (0xff, adjustable)
* GsmStringAdapter(Adapter): Codec for "SMS default 7-bit
	coded alphabet as defined int TS 23.038" using
	the gsm0338 library.
* GsmString(n): Convenient wrapper of both above

Adjustments:
* utils: update+deprecate old dec_spn(), enc_spn()
* remove refs to deprecated functions

Harald Welte 4ae228afc7 Implement EF.ARR (Access Rule Reference) decoding
The Access Mode (AM) and Security Condition (SC) DOs are incredibly
convoluted, so we need a lot of code to properly decode them.

Harald Welte e0f9ef1606 integrate 'construct' python library
'construct' is a declarative symmetric encoder/decoder for user
specified binary formats.  It should come in extremely handy in
tools like pySim.

We start the integration by adding transport methods for transceiving
APDUs with built-in encoding of the command data and decoding of the
response data.
