Upgrade to support Bearer authentication

[transitive-bullshit]

It seems that TMDB now supports the standard Authentication: Bearer <token> scheme, but this package still relies on the api_key query param.

Hey, so sorry I'm just now responding to this. I'm usually a lot faster...

It looks like using you can use the header with a "API Read Access Token". We'd probably have to have a way to distinguish on which token type you're using?
