gsm_abis_om2000: Dissect TLV structure of 0xa3/0xa5/0xa6 TLVs
We have no idea what those TLVs are, but the message hex-dumps clearly
indicate a 8-bit tag followed by 8-bit length and then 'length' amount
of bytes, so we can at least dissect that high-level structure for now.
They appear in equally unknown message type 0x126, which appears to be
sent in intervals of 300s by the RBS.
