enable usage of pyproject.toml

[Bloodmallet]

Enable a pyproject.toml to prepare a library to use setuptools-got-versioning.
In addition I added some code to enable settings for this library to be collected under the libraries name. Therefore one can now write the following in the known setup.py:

setuptools.setup(setuptools_git_versioning=True, setup_requires=["setuptools-git-versioning"], ...)

Documentation was adjusted accordingly.

fixes the spirit of #35

Please let me know, what your opinion is and what you think might be necessary to get this merged and released. I like the library and would like to keep using it, even thought the usual setup.py is depricated now. Using a pyproject.toml file is the way to go.

Seeing multiple failures for old python versions due to the used library "tomli". I could brew my own toml reader if necessary. How important is the compatibility with those old python versions?

Hello, thank you for the PR!

It looks like toml package does support 3.3 and 3.4

Indeed. I changed the PR to use toml instead. I forgot to remove my comment.

I've dropped support of 3.3 and 3.4 in the master branch. CI/CD pipeline is very unstable because of them, and also there is no actual need to spend so much time to support these versions. So you can return tomli back.

I'm also thinking about dropping support of 2.7-3.6 in some future release, but let's merge this PR first

[Bloodmallet]

Thank you very much. If you have some holiday days currently: enjoy. And in any case: Take care.

[Bloodmallet]

Oh! You updated my branch. I misunderstood the merge. I'm reopening the Pullrequest and hope for the change/update merge into your repository.
