Addition of CircleCI hook?

[jrdnbradford]

Any interest in a CircleCI pre-commit hook? A schema exists at SchemaStore/schemastore and it seems to fit the other CI/CD-related hooks. I can put in a PR if interested.

I'm always happy to add more hooks -- I'd gladly look at a PR!
Because there are so many possible schemas and hooks to add, my general attitude has shifted to an "as requested" basis for adding them.

I'd eventually like to reposition this so that check-jsonschema derives most or all of its hooks from a data package with all of schemastore in it. I started on this as a possibility and some other folks did too, but there are some issues which need to be sorted out (correct licensing, automatic update and release process, and then managing reproducibility in pre-commit).
