Last.fm has removed many API endpoints over the years. This removes all
  methods and classes that call endpoints now returning error 3 (Invalid
  Method), aligning the library with the current API surface.

  Deleted classes (all methods called removed endpoints):
  - Event, Group, Playlist, Radio, Tasteometer, Venue
  - BuyLink, Shout, Image (supporting types only used by removed methods)

  Removed methods from surviving classes:
  - Album: getBuylinks, getShouts
  - Artist: getEvents, getPastEvents, getImages, getTopFans, share, shout, getShouts
  - Chart: getLovedTracks, getHypedTracks, getHypedArtists
  - Geo: getEvents, getMetros, all getMetro*Chart methods, Metro inner class
  - Library: addArtist/Album/Track, removeArtist/Album/Track/Scrobble, getAlbums, getTracks
  - Tag: search, getWeeklyArtistChart
