sigProcLib: introduce both TS1 and TS2 RACH synch. sequences
According to 3GPP TS 05.02, section 5.2.7, there are three
synch. sequences for Access Bursts:
- TS0: GSM, GMSK (default),
- TS1: EGPRS, 8-PSK,
- TS2: EGPRS, GMSK.
Let's prepare everythyng to be able to detect all TS0-3 synch.
sequences, but keep detection of both TS1 and TS2 disabled
until the corresponding VTY option is introduced.
