Discard commits in commit_preprocessors or similar extension point

Is your feature request related to a problem? Please describe.
I want to discard commits after git-cliff has extracted the range of commits. The commit_preprocessors exists but I am not sure if that is possible, its probably the wrong place.

Describe the solution you'd like

I think a commit_filter section similar to the commit_preprocessors might be useful, with the ability to run some custom commands. We have some internal tool which can detect if a commit should be included in the changelog, basically for the monorepo usecase. It would be nice to specify

{ filter_command: "detect-if-commit-is-included.py" }

which will get --input input.yaml which contains all commits

commits:
  - 123123123123123...
  - a12312312341212...

and myspecialtool.py outputs the filtered new list to input.yaml which then will get taken care of by git-cliff.

One could also think of the commit_filter run after parsing the conventional commits, so we would already have more input, basically handing over the whole template context to the command.
