Add precommit hooks

**Is your feature request related to a problem? Please describe.**
It would be a better developer experience if lint checks were run as a Git precommit hook, as opposed to the somewhat longer feedback loop of a CI failure.

**Describe the solution you'd like**
Many such tools/toolchains exist on NPM, `lint-staged` and `husky` being the most popular.

`lint-staged` allows for linting only staged files, and `husky` sets up Git precommit hooks in your project.

Additionally, tools such as `commitlint` can be used to enforce Git commit message styles (in this case, conventional commits) while `commitizen` can be used to provide a CLI wizard for commit messages.
