A CLI tool for reverting changes made in a Launchpad merge proposal. Does roughly the following:

1. Given a link to a merge proposal (--mp-to-revert), figure out into which branch it was merged
2. Check that branch out and pull
3. Create a new branch (with the name being branch name --new-branch-suffix)
4. Revert the merge commit
5. Push the new branch with the revert to upstream specified by --upstream
6. Create a new merge proposal against the same branch the original MP was merged into

1. Clone the repo
2. pip install --user .
