So for some weird historical reasons, the same python module is
available as pycryptodome (Crypto.* namespace) and pycryptodomex
(Cryptodome.* namespace). See the following information on the project
homepage: https://www.pycryptodome.org/src/installation
To make things extra-weird, Debian choose to package pycryptodomex as
python3-pycryptodome
(https://bugs.debian.org/cgi-bin/bugreport.cgi?bug=886291).
So in order to support both Debian-packaged and differently-installed
packages, let's switch to pycryotodomex on all platforms/installers.

When using AES CMAC for authentication of OTA messages, we must not pad
the user data before calling the CMAC function. This is unlike the DES
MAC, where padding to the DES block size is mandatory.
This bug was discovered when trying to talk OTA with AES to a
sysmoISIM-SJA5. This patch makes the OTA AES interoperate with the
card. Also, with this patch the cryptographic results of pySim/ota.py
are identical to those of the java code

This introduces a hierarchy of classes implementing
* ETS TS 102 225 (general command structure)
* 3GPP TS 31.115 (dialects for SMS-PP)
In this initial patch only the SMS "dialect" is supported,
but it is foreseen that USSD/SMSCB/HTTPS dialects can be
added at a later point.
