Ultris Bug Fixes

A tiny, simple addon mod/datapack for Ultris: Boss Expansion that fixes a few bugs.

It currently fixes:

• Using Corrupt Dust on an enderman. Before then, provoking a fight with the Corrupted Enderman when converted using Corrupt Dust has it cut straight into its desperation phase. With this mod installed, using Corrupt Dust will finally have the fight initiate properly the way it should.
• The Corrupted Enderman's boss bar max value not actually matching the max health value of the boss, causing the first few blows against it to not budge its boss bar at all.
• The Ultra Wither's command block having a hitbox of its own with active collision, which can obstruct the boss's own wither skull projectiles.

Please let me know if there are any other bugs pertaining to Ultris that I have yet to take care of!
