[REF] Deprecate pkg_resources, use importlib & packaging (#121)

* [REF] Switch version detection from `pkg_resources` to `importlib,packaging`

* [REQ] Add `packaging` as dependency

* [CI] Install `packaging` before installing package

* [CI] Try installing with `python -m pip`

* [FIX] Try CI with python 3.9

* [FIX] Try installing `packaging` with `apt-get`

* [FIX] Call `pip show`

* [FIX] Try with `python3.10`

* [FIX] String around python version

* [FIX] Try installing `wheel`

* [FIX] Explicitly install `wheel`

Magically seems to fix the import error of `packaging`

* [FIX] Also explicitly install `packaging`

* [FIX] Install `wheels` and `packaging` in RTD

* [FIX] Different install command

* [FIX] Another attempt

* [FIX] Spelling error

* [FIX] Try again

* [FIX] Try with `post_build` option

* [FIX] Use `post_install`

* [FIX] Install `setuptools<=69`

* [FIX] Pin `setuptools`
