Version via Git tags only

[phinate]

Using setuptools_scm. Makes our versioning workflow use git tags, which we can control through GitHub releases.

The workflow is:

• PR(s) get merged
• Make a github release with a new tag (+ auto-generate release notes)
• Version will be implicitly updated once you run git pull after the tag creation!
  • you can check this with python -c "import cloudcasting; print(cloudcasting.__version__)" :)

Also important: this needs you to always include a patch version, e.g. v3.0.0, or the wrong digit will get updated (see here)

Looks good
