DEP: setup.py deprecated by pip

[jklenzing]

Is your feature request related to a problem? Please describe.
From the unit tests at pysatCDAAC:

 DEPRECATION: pysat is being installed using the legacy 'setup.py install' method, because it does not have a 
'pyproject.toml' and the 'wheel' package is not installed. pip 23.1 will enforce this behaviour change.

Describe the solution you'd like
pyproject.toml

Describe alternatives you've considered

I'm very close to a functional version of pysatNASA using pyproject.toml. Two problems left to solve:

• NEP 29 compliance
• pysatCDF install

I may may try on another package first to simplify dependencies

Sample version up at pysat/pysatCDAAC#39

From the test cases so far, I've been able to consolidate metadata / settings info from 5 files to 2.

Dropping open pulls down to drafts until we can discuss at the next meeting. Comments/questions are welcome. Currently researching background more.

Notes from discussion today:

• use setup.cfg instead of tox.ini
• maintain setup.py for backward compatibility
• research parsers for readthedocs integration

pip 23.1 has been released and is wreaking havoc in the tests. This issue should be accelerated.

[jklenzing]

Some things that are relevant to our build processes for pip 23.1.0 (Released 4-15-2023). From https://pip.pypa.io/en/stable/news/

--no-binary does not imply setup.py install anymore. Instead a wheel will be built locally and installed.

--no-binary does not disable the cache of locally built wheels anymore. It only means “don’t download wheels”.

Remove setup.py install fallback when building a wheel failed for projects without pyproject.toml.

When the wheel package is not installed, pip now uses the default build backend instead of setup.py install and setup.py develop for project without pyproject.toml.
