Gnss-lib-py

In line with user requests, we are now updating our GNSS library to support Python 3.12! The library is still compatible with Python 3.9, 3.10, and 3.11 across Linux, MacOS, Windows, and Google Colab (Python 3.10). But, if you wish to continue using Python 3.8, we recommend that you stay with v1.0.2.

Version Changelog:

- Added compatibility for Python 3.12 and removes compatibility for Python 3.8, addressing 164
- Updated functions in `gnss_lib_py` to enable Python 3.12 compatibility
- Expanded tutorials and documentation throughout

I hope you all enjoy the new release!

Excited for a new release of `gnss_lib_py` integrating new functionality and patching some user-identified bugs!

Version Changelog:
- Convert elevation and azimuth to ENU unit vectors
- Compute DOP for NavDatas with elevation and azimuth data
- Patched bug where `NavData` and `Visualizations` modules were not in `ReadTheDocs`.
- Removes NaN rows that `georinex` outputs when parsing Rinex Nav data files
- Fixes 155
- unifies the conftest.py testing file for all modules
- checks for NaN pseudoranges in EKF
- adds `navdata` and `visualizations` to code coverage
- adds test for returning NaN values in an int array

Minor bug fix:
1. Fixes initialization of `num_cols` when `NavData` is initialized.

Related updates made to docs and tests

We are finally releasing version 1.0.0! This release changes file and directory structure to improve the longevity of the codebase and allow for continued expansion of its capabilities.

No significant changes will need to be made in code for users using the `import gnss_lib_py as glp` convention except for the instances of the `concat`, `sort`, `loop_time`, `interpolate`, and `find_wildcard_indexes` functions which used to be class functions of `NavData` but are now independent functions with the first argument being the `navdata` object(s) on which to perform the action.

Detailed Changelog
- breaks navdata into `navdata` and `operations`
- rewrites `concat`, `sort`, `loop_time`, `interpolate`, `find_wildcard_indexes` so their independent functions and not class functions
- adds `concat` ability to concatenate an arbitrary number of NavData instances rather than just two
- breaks out components of visualizations into independent files
- updates ReadMe, etc. with updated directory structure
- creates uniform tutorial structure with a notebook file at least for each file in `gnss_lib_py`
- updates python packages

This release mainly expands robustness of the automatic ephemeris downloader, extends compatibility of the `rinex_obs` parser to all observation codes, and adds parsers for raw android data.

Ephemeris Downloader
Expands file download options to enable downloads for:
- `rinex_nav`: present - Jan 1, 2013
- `sp3` : present - May 24, 2012
- `clk` : present - Oct 14, 2012
Also adds secondary sources for `WUM0MGXFIN` clk, `wum` clk, and `BRDM00DLR_R` rinex nav for outlier days when those files weren't uploaded to CDDIS
Rinex Observation Files
- allows rinex_obs to load all possible observation codes
- z-tracking observations may have empty `carrier_phase` and `raw_doppler_hz` rows
- fixes 139
Android Raw Files
- differentiates the Google Smartphone Decimeter Challenge into `google_decimeter.py` and GNSSLogger parsers into `android.py`
- updates unit_test directories according to the above change
- adds parsers for data obtained from the GNSSLogger Android app including`Raw`, `Fix` and all sensors
- adds recommended filters for raw GNSS data from android phones
- adds new NavData classes for the 2023 version of the Google Smartphone Decimeter Challenge
Miscellaneous
- updates python package dependencies
- minor bug fixes
- minor doc updates

This release focuses on improvements to visualizations and adding two fault detection and exclusion methods.

Full changelog:
- changes plot titles to be Y vs. X
- adds option for averaging multiple y values across x
- better skyplots across long time horizons where satellites coming in and out of view
- adds Greedy EDM fault detection and exclusion
- adds Residual EDM fault detection and exclusion
- adds fde testing and documentation
- allows solve_wls() to handle empty measurements being passed in
- saves navdata CSVs to the same default results directory as visualizations
- prints requested input path if the file is not found when loading any file for help in debugging
- updates python package requirements
- adds ``open in colab`` badge
