Monarch Wings 1.1.0 for Minecraft 1.20.2

• Update for Minecraft 1.20.2.
• Make it so when a player is able to double jump, their elytra will be visually poised to flap, returning to their original position once double jumping is no longer possible.
  • To facilitate this, whether a player can double jump has been painstakingly synced between the client and the server. Please report any bugs to me by making an issue on Github.
• Refine exactly when a player is able to double jump.
  • I expect these changes should be immaterial to most/all players.
• Many mixins were migrated to use MixinExtras where applicable.
  • This should allow us to be compatible with more mods.
