gsm0808: add knowledge of TW-TS-003 BSSMAP IE
Themyscira Wireless Technical Specification TW-TS-003 adds a non-standard IE to GSM 08.08 BSSMAP whose purpose is to signal the use of enhanced RTP payload formats that go against the stipulations of TS 26.102 (referenced from 48.103 for AoIP), but allow an IP-based GSM network implementation to mimic the workings of TDM-based GSM more faithfully.
