Fixes the TOW computation mapping from GLONASS Time to UTC time and then
conversion to TOW and WN. The logic of the conversion considers time
offsets but may need to be reviewed.
Forces conversion of semicircles to radians units in some GNAV Almanac
parameters. In addition, adds safeguards in code to avoid invalid
slot number identification.
Adds code to solve the shared frequency channels for GLONASS satellites
during acq and trk, it is now decode responsability to fix the identifier
when decoding of ephemeris happens. It also adds more details in tracking
plotting and fixes silly bug that created false alarm.
The code fixes the computation of the carrier frequency for pcps
acquisition of GLONASS satellites by making it relative to the IF. Also
new plotting features are added to visualize results
