    sigProcLib: Fix burst start phase.
    
    R&S CMD57 complains about the start phase of bursts, particularly it shows
    -15 to -30 deg of error for the bit 0.5 position (start tail bit). This patch
    makes it happy. ETSI TS 145 004 section 2.2 describes this: "Before the first
    bit of the bursts as defined in 3GPP TS 45.002 enters the modulator,
    the modulator has an internal state as if a modulating bit stream consisting
    of consecutive ones (di = 1) had entered the differential encoder."
