sigProcLib: add a CorrType for extended (11-bit) RACH

This is a preparatory change that enables a possibility to choose
the amount of synch. sequences to be used for Access Burst (RACH)
detection. The VTY flag will be introduced in further changes.

There are two correlation types now:

  - RACH (default) - TS0 only;
  - EXT_RACH - all TS0, TS1, and TS2 together.
