Carles Fernandez 028ebe433d QZSS: refine L1 C/B support 
- Restore true chip semantics for L1: QZSS_L1_CHIP_RATE is 1.023 Mcps and
  QZSS_L1_CODE_LENGTH is 1023 chips again. The replica carries
  QZSS_L1_SAMPLES_PER_CHIP = 2 samples per chip (L1 C/A chips duplicated,
  L1 C/B sinBOC(1,1) subchips), following the Galileo E1 approach. The
  generated waveform is unchanged, but Tracking_1J.early_late_space_chips
  is expressed in chips again, consistently with all other signals.
- Normalize the DLL discriminator with the sinBOC(1,1) correlation
  function when the tracked PRN broadcasts L1 C/B, selected per PRN in
  start_tracking(); warn if the configured correlator spacing falls
  outside the BOC(1,1) correlation main peak (> 0.33 chips).
- Attribute L1 C/B observables and ephemerides (PRN 203-206) to the PRN
  of the satellite's nominal PNT signals (RINEX 4.00, Table 6), so RINEX,
  RTCM and rtklib identify the transmitting satellite correctly and
  multi-frequency observations of the same satellite are paired instead
  of counted twice.
- Do not search QZSS L5 signals for PRNs above 202, which have no L5
  PRN code assigned in IS-QZSS-PNT.
- Remove reserved, non-operational PRNs 198 and 202 from the default
  QZSS search list; they remain selectable via the QZSS.prns option.
- Fix a potential std::out_of_range in
  GNSSFlowgraph::priorize_satellites() when assisted acquisition
  prioritizes satellites of a constellation with only a subset of its
  signals configured.

Vladislav P 1146a5285c QZSS: L1C/B implementation 
Increase QZSS L1 chip rate to 2.046MHz to handle L1 C/B BOC(1,1)
sequences
Increase QZSS L1 code length to 2046 to handle L1 C/B BOC(1,1)
sequences
Increase maximum QZSS PRN to 206
Implement optional BOC(1,1) sequence generation
