Enable/disable pre-commit hooks

Pre-commit hooks help keep the codebase consistent by auto-formatting with black and isort whenever you commit. The goal is to reduce git diffs so that comparing histories is much easier, but pre-commit hooks can get in the way when merging/rebasing. I recommend only disabling when you really need to, to prevent 'catch-up' styling commits.

• Enable with pre-commmit install
• Disable with pre-commit uninstall

Splitting up a commit in a branch

Use case: You combined unrelated changes into the same commit and want to split them for readability or reducing diffs

1. Checkout the branch that you want to modify (e.g. pj/feature)
2. Start an interactive rebase which includes your commit. - At a minimum, git rebase -i commit^ will start the rebase at the commit you want to split - You can also rebase the whole branch, which I usually do to split all target commits in one go
3. Mark the commit(s) that you want to split with edit
4. When git presents the commit that you want to split:
   1. Reset state to the previous commit using git reset HEAD^
   2. Use git add to carefully and incrementally add changes to the index
   3. Run git commit when you have a set of atomic changes that you are ready to commit
   4. Repeat the git add and git commit process until you have processed each set of changes represented by the commit
5. Run git rebase --continue to resume or finish the rebase
