output NAV2/3 iono parameters, use updated pytest 3.9+ fixtures

Improved output of NAV 2/3 parameters, especially ionospheric parameters.

Corrected NAV test file spacing issues

Use Pytest ≥ 3.9 tmp_path fixture.

BUGFIX mangled NAV3 data, plot galileo NAV

• BUGFIX #30 for irregular NAV3 data for Galileo
• functionalize irregular NAV3 data handling/checking
• plot galileo nav

Handle OBS2 mangled header/data times, dedupe

Fixes #29 mangled times in header and data. Dedupe time conversion for header

BUGFIX: NAV2 crash for irregular length (missing FitIntvl), improve GNSS location plots

• allow NAV2 files to intermittently be missing the final field (e.g. GPS FitIntvl)
• allow reading .nc files as well as RINEX for location plotting

Auto-allocate is smarter, reduced memory, auto-off

• Added pre-scan to autoallocation to reduce RAM usage by not always using absolute worst case.
• added auto-off (fast=False) if autoallocation senses file has an unusual/non-standard format
• dedupe code
• add obs.fast_processing=1 or 0 to indicate file was processed with fast=True or False respectively.

Fast allocate OBS2

• fast=True default fast allocate based on file size and minimum SV=6 on average for OBS2
• quick check to see if RAM exceeded in OBS2 reads

BUGFIX: missing header elements, minimal files, location plotter

• BUGFIX: handle (avoid crashing on) RINEX 2/3 OBS/NAV files with extremely minimal headers and missing data sanely
• optional location plotter, with optional output of geodetic GNSS receiver coordinates

Batch conversion, rigourous exceptions, more test coverage

make rnx2hdf5 its own program to make use more obvious, with rigorous cross-platform test coverage
