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
