Better Skeletons

This is my first datapack and I am still working on creating better mobs.
This datapack adds in harder skeletons that replaces the old boring skeleton.
After this datapack is enabled into your world, these skeletons will natural spawn frequently in your world.

There is 5 different types:
  - Diamond armor
    -Has very high defense
    -Flame bow

  - Invisible
    -Very powerful
    -Can only see its bow

  - Magical
    -Rides a spider and is in black leather
    -Will blind and slow you if too close

  - Skeleton hoard
    -Wooden axe
    -Spawns in large groups
    -Super fast

  - Iron armors
    -Spawns in groups of 3
    -Has good defense

Comment if I should add more or if I should do a different mob or maybe add onto this one!
