Fixing CurrentUsersTracksOpt market query parameter + proper handling of results

[fclairamb]

Thank you for this great lib.

• The me/tracks API uses the market query parameter instead of country.
• When the market query parameter is passed, an is_playable and linked_from key is returned.

Updating all the API to support track relinking:

• [x] Get a Track
• [x] Get Several Tracks
• [x] Get an Album
• [x] Get Several Albums
• [x] Get an Album’s Tracks
• [x] Get a Playlist’s Tracks
• [x] Get a User’s Saved Tracks

Hi @zmb3, so what is the next step? Do you want me to change something or can we merge it as-is?

Sorry @fclairamb I didn't see your reply 😬

The web API docs show that the following calls support track relinking:

• Get a Track
• Get Several Tracks
• Get an Album
• Get Several Albums
• Get an Album’s Tracks
• Get a Playlist’s Tracks
• Get a User’s Saved Tracks

It looks like "country" is not valid for any of those, so I am fine overriding "country" in these cases to be used for track relinking, so long as the godoc makes that clear.

I do think it makes sense to get all of these calls supporting track relinking together though, rather than leave things in a state where relinking works for some things but not others. Are you up for making the same changes in all of these places? I don't mind if it's part of the same PR or separate ones, so long as they all get updated in the same 1-2 days.

Wowkay, I guess I can do that. I indeed only focused on fixing the parts where I needed this feature.

Hi @zmb3, so I finally took the time to update the other parts of the library where the market parameter can be used.

Please note I broke the GetAlbumTracksOpt API because it's the only one of the *Opt function that didn't receive an *Option parameter. I think it's worth it here.

Thanks @fclairamb for taking the time, and happy new year!
