Fix the $TSFixMe (any alias) type definitions

[himynameisdave]

Fix all the $TSFixMe (alias for any) type definitions by providing real type definitions for them.

This was added as a placeholder because there were a few places where I didn't know the best way to define types.

I would like help with this issue, not just to have stronger typing in this package, but also as a learning exercise so that I better understand complex typing.

Acceptance Criteria

• Fix all the cases of $TSFixMe
• Explain what has been changed
