Vadim Yanitskiy 29ca8049d6 Implement Generic SIM Access interface as per 3GPP TS 27.007

According to 3GPP TS 27.007, sections 8.17 and 8.18, the modem
may *optionally* provide Generic and/or Restricted SIM Access
to the TE (Terminal Equipment) by means of the AT commands.
This basically means that a modem can act as a card reader.

Generic SIM Access allows the TE to send raw PDUs in the format
as described in 3GPP TS 51.011 directly to the SIM card, while
Restricted SIM Access is more limited, and thus is not really
interesting to us.

This change implements a new transport called ModemATCommandLink,
so using it a SIM card can be read and/or programmed without the
need to remove it from the modem's socket. A downside of this
approach is relatively slow I/O speed compared to PC/SC readers.

Tested with Quectel EC20:

  $ ./pySim-read.py --modem-dev /dev/ttyUSB2
