Mkchangelog

Features

- **bump:** allow to `--set-versions x.y.z` to force next version

Refactors

- **core:** split code into parser/output/main modules

This release had only `Chore` and `Docs` changes,
so with my config `commit_types_list = fix,feat,refactor` this
version release notes are empty.

And this message comes from `.mkchangelog.d/versions/v1.0.3/header` file.

Features

- **providers:** Artifical / external commits provider

Apart from custom version header you can also put footer (under all version changes)
by creating `.mkchangelog.d/versions/v1.0.3/footer` :).

Fixes

- **core:** make project working with python 3.7 and 3.12

Fixes

- **bump:** proper Version sorting

Refactors

- **core:** use optional rich for colorized output
