Hello thanks for this package.
I recently started to use lib python-semantic-release and it needs correctly formatted commits to work well.

2 suggestions to your README.md :

• mention it is python 3 only. I first did a pip install that failed but pip3 install succeeded
• mention that the convention used by default in the hook is the Angular Commit Message Conventions

To add to this, conventional commits are case-insensitive and this script is case-sensitive. This may be in point with the Angular Commit Messages Conventions mentioned above but it needs to be pointed out that this is against the docs of conventional commits.

The units of information that make up conventional commits MUST NOT be treated as case sensitive by implementors, with the exception of BREAKING CHANGE which MUST be uppercase.
