Ultris: Boss Expansion

The Ultra Wither's big staring, the Sanctum Keeper's phase 2 intro's 4th version!!! And Shulker Stone lasers are now longer loud?!?!?!?

- Ultra Wither now has a laser attack! It'll explode its surronding area first, then slowly shoot out slow moving lasers everywhere
- Ultra Wither now gives clearer indication of its starting shield, and clearer indication of final hit section
- Revamped the Sanctum arena a bit better, gave it a bit more space and decor
- The Sanctum Keeper phase 2 center teleport phase has been changed to be a lot more random and fast paced
- Sanctum now generates in the same biome tag as strongholds for better compat with other datapacks
- Sanctum Keeper can now heal itself MUCH stronger, BUT you can prevent it from healing by breaking its potion (hit it whilst its drinking it!)
- Sanctum Keeper no longer drops instant damage potions as an attack
- Shulker Stone center defend give more warning now
- Shulker Stone lasers are no longer super loud
- Corrupted Endermans now hit you with their hands
- Shulker Stone lasers have been redone, code wise and animations changed
- Ominous eye of ender now has a slight delay before teleporting back to the nearest player
- Ultris music is now all Stereo based rather than Mono meaning the audio quality and tone should be heard much better (for @_humanoid#9099 )
- Sanctum Keeper music "Fury of the Spirits" got slight improvements
