Incorporates the fixtures from eslint-plugin-react-hooks using a script, so that we can easily update them in the future. For each fixture we run the compiler with and without hooks validation first so that we know if the fixture is expected to pass — we have some false positives and false negatives that i can work through. For example we accidentally think that `userFetch()` is a hook, oops. Fixtures that should pass but error, or that should error but pass, are marked as `todo.<name>` or `todo.error.<name>`. While i was here i added the ability to have fixtures in subdirectories for grouping purposes.
