Create Recommendations albums, and playlists helper methods

[rudrankriyam]

let albums = try await MusadoraKit.recommendationAlbums() 

let playlists = try await MusadoraKit.recommendationPlaylists()

It does not seem to make sense as each recommendation is a different struct with unique properties that contain the relevant collection of albums, playlists, or stations.
