r3l3453 0.28.0

Bump version, tag, commit, release to pypi, bump again, and push.

r3l3453 is a small project that I use for semi-automating release cycle on a few projects of mine.

In short what it does is as follows:

• Bump version(s) to a release version according to git log and Conventional Commits.

• Change the title of Unreleased section in CHANGELOG.rst to the new version.

• Commit changes.

• Tag the commit.

• Release to PyPI.

• Bump the version again to dev0 version for the next release.

• Push changes to repository.

There is a --simulate cli option which allows one to see what is going to happen.
