MprisCustomHud

Breaking changes:

• renamed mpris_track_id -> mpris_trackid and mpris_loop -> mpris_repeat
• previous Special variables are now Numbers
• time variables are no longer in seconds but now in milliseconds (mpris_duration and mpris_progress changed)
• preferred key in the config now saves the complete bus name
  • just set the preferred player again via the command
• replaced the filter key in the config with a onlyPreferred key that effectively turns preferred into filter

Changes:

• added Hudder support for Minecraft >= 1.21.9
• added mpris_data_age variable
• added has_mpris, mpris_player_info and mpris_players variables to Hudder only
• added getPlayerInfo function to Hudder
• switched to official mappings + stonecutter to support 26.1
• improve code lol (I reworked many things)
