This version builds to wheels on both Windows-intel64 and MacOS-arm64, and moves development closer to full support of das3 streams.
Updates
Updates for this version include:
* Building against [das2C version 2.3.0](https://github.com/das-developers/das2C/releases/tag/v2.3.0), thus incorporating those updates.
* Updated project configuration files to conform to recent [setuptools](https://setuptools.pypa.io/en/latest/setuptools.html) standards.
* A das_verify script for validating das 2.2 and 3.0 streams including v3.0 pure XML documents as well as
mixed XML and binary streams with, and without, XML namespace tags.
* Passes tests with numpy 1.21 (hat tip to KaiwenS7)
* Added new example [ex09_cassini_fce_ephem_ticks.py](https://github.com/das-developers/das2py/blob/main/examples/ex09_cassini_fce_ephem_ticks.py) which demonstrates adding spacecraft ephemeris information to X-axis tics.
* Added TT2000 output support for DasTime.epoch()
* Added a das3 stream extension [example](https://github.com/das-developers/das2py/blob/main/test/ex13_object_annotation.d3t) that encapsulates [Autoplot](http://www.autoplot.org/) annotations.
* Added a das3 stream extension [example](https://github.com/das-developers/das2py/blob/main/test/ex14_object_tfcat.d3t) that encapsulates [TFCat](https://maser.lesia.obspm.fr/publications/doi/doi.html) entries in das v3 streams.
Dependencies
* [lxml](https://lxml.de/) for parsing headers and/or documents in the das_verify script
* [matplotlib]() for the das2.mpl extensions
* External [libcdf](https://cdf.gsfc.nasa.gov/) binary for exporting data to CDF
* And of course [numpy](https://numpy.org/) and [das2C](https://github.com/das-developers/das2C), for fast binary stream handling.
Recognition
The binary CDF library wrapper was not produced by das-developers, but rather as part of the [spacepy](https://github.com/spacepy/spacepy) project. Thanks to spacepy for creating a very useful module to support space physics.
