gsm_04_08: add parser for Mobile Station Classmark 3
3GPP TS 24.008 section 10.5.1.7 describes a Mobile Station Classmark 3
IE, which is encoded as CSN.1 struct. This means that it can not be
parsed by just casting a memory location to a struct pointer, so lets
add a parser to parse the CM3 IE.
This is fixed version of Ic8b2bfd00330235f5bed00771e421588abfaac1f,
which got reverted because it used the keyword "class" as struct member,
which lead into problems with c++ builds. This is now fixed.
