Mac Deprecation warning

[jzstoller]

The mac installation instructions still work well but throw a deprecation warning on this step:
pip3 install "shapely<2" --no-binary shapely

The warning is:
DEPRECATION: --no-binary currently disables reading from the cache of locally built wheels. In the future --no-binary will not influence the wheel cache. pip 23.1 will enforce this behaviour change. A possible replacement is to use the --no-cache-dir option. You can use the flag --use-feature=no-binary-enable-wheel-cache to test the upcoming behaviour. Discussion can be found at pypa/pip#11453

Hopefully #2083 will land well before that deprecation becomes a problem and we won't care about how Shapely is installed any more.

We have just released v0.22 which should help with the compatibility between packages and installation much easier. Please open a new issue if you are still having problems.
