This PR tries to update requirements / python setup to more recent versions (>=3.7).

1. pyproject.toml file
   • dependencies and metadata are defined in the toml file (setup.py & requirements deprecated)
   • scripts / entrypoints are defined here as well (bin folder deprecated)
   • wheels are built setuptools / toml file now (python >= 3.7)
   • deeptools' version is defined in the toml file as well (no more _version.py, keep importlib as a requirement until we drop python 3.7 support).
   • --version flags have been changed to use importlib in all executables.
   • matplotlib version pin has been removed, some changes in the cm.py for newer version.
2. CI / github actions
   • nosetests are deprecated and ported to pytests
   • pytests now run on proposed wheel with version 3.7 - 3.11
   • dependency on the custom typescript action (https://github.com/deeptools/github-actions) has been deprecated in favor of micromamba/python/miniconda-setup actions
   • planemo tests and pytests use conda environment(.github/test_and_build.yml), historical 'foo' name is dropped.
   • planemo tests expected pngs are slightly changed (due to mpl updates)
   • expected qual metrics in plotfingerprint changed, not 100% where exactly the rounding difference comes from
   • planemo tests run on galaxy 23.1

@bgruening Do you mind having a look ?
I'm not sure if the change to 3.10 will bring some difficulties especially with the galaxy version ?

Cool, a few comments inline :)

Thanks @WardDeb

we could test multiple versions if we like.
Historically we tested for the lower bound. But we could test for lower and upper-supported python versions.

3.8 and 3.11?

[WardDeb]

I've included 3.7 & 3.11, though I'm not sure how relevant it is at this stage (planemo_combine_outputs): The tests have already ran at that time, right ?

Very nice. Thanks a lot @WardDeb
