Feature Request: Company data

[benlei]

Is your feature request related to a problem? Please describe.

Right now it seems like this library is missing the ability to fetch company details/alternative names/images. Can this be added in?

This would be for the following endpoints:

• https://developer.themoviedb.org/reference/company-details
• https://developer.themoviedb.org/reference/company-alternative-names
• https://developer.themoviedb.org/reference/company-images
