"Slipping" a new elytra enchantment

Slipping would be an enchantment for only Elytras

It goes to Level I, II, III, IV

Basically, when you have slipping it makes it easier to survive while flying

When flying into something like a wall or ground, slipping will divert some of the damage you would have taken and simply shoves you in a different direction, almost like you're "slipping" across the blocks you just hit

At first Slipping would be pretty weak, Slipping I would only give you a slight boost to your speed when travelling at gliding speed and hitting the edge of a block (no firework boosts)

Slipping II would be better, allowing you to use the slipping mechanic to keep your momentum by bouncing off walls (NOTE: Slipping also relies on where you hit the block, hitting it dead on wont do much, the closer to the edge of a block you are the bigger speed boost and the less damage you take, if you hit the VERY EDGE of a block you will take no damage and get a speed boost) which could be used for really fun parkour

Slipping III, IV will do the same, just with more damage reduction and a bigger margin for error

Slipping could be either in the enchant table or an adventure mechanic, but to make it more fun i suggest it can be found only in the end making it an extremely rare but useful enchant
