Add watch endpoint

[joelhenryclark123]

Watch Providers endpoint!

I added support for the watch providers endpoints. The endpoints return the full list of supported region codes & the full list of watch providers.

Additions

• New types: Region and WatchProvider
• Watch Providers endpoint added to the TMDB class
  • Includes 3 GET endpoints: regions, tv providers, and movie providers

Benefit

Lets you store the watch providers in your own database

Test it out

const tmdb = new TMDB(<api key>);

// List the names of all the movie providers in the US
tmdb.watchProviders.getMovieProviders().then(response => {
  response.results.forEach(provider => {
    console.log(provider.provider_name);
  });
});

// Get regions in english
tmdb.watchProviders.getRegions().then(console.log);

// Get regions in german
tmdb.watchProviders.getRegions('de').then(console.log);
