Carles FernandezandClaude Fable 5 4f570e7867 Store QZSS UTC and iono parameters separately and log RINEX 4 QZUT records
The Klobuchar coefficients and the UTC(NICT) offset broadcast by QZSS
satellites in LNAV subframe 4 (both the wide-area and Japan-area pages)
were stored in the shared GPS structures, overwriting the GPS-sourced
values in mixed GPS + QZSS configurations and making it impossible to
label them correctly in RINEX output.

New Qzss_Utc_Model and Qzss_Iono storage classes are now published by
the QZSS-configured L1 C/A telemetry decoder and kept in dedicated
Rtklib_Solver members. With this in place:

- RINEX 4.02 navigation files get "> STO J  LNAV" QZUT records with the
  UTC(NICT) identifier and "> ION J  LNAV" Klobuchar records, and the
  LEAP SECONDS header is updated from QZSS data in QZSS-only setups.
- QZSS-sourced parameters are no longer mislabeled as GPS corrections
  (GPUT / GPS ION or TIME SYSTEM CORR / IONOSPHERIC CORR lines).
- The QZSS slots of the RTKLIB navigation structure (utc_qzs, ion_qzs)
  are now populated; QZSS-only configurations keep feeding the broadcast
  ionospheric model and the leap second count as before.
- The XML storage output gains qzss_utc_model.xml and qzss_iono.xml.
