Useful Slime (Forge) 1.9.0-1.20.2

There will be no backports of this version (even to 1.20.1) due to missing dependencies

Added a maximum speed for slime blocks (with a config)
Reduced Slime Sling strength in water
Climbing with slime armor now plays slime block step sounds
Slime Helmet will protect against damage when flying into a wall with elytra. This does not include flying into the ground (use Slime Boots for that)

Fixed Slime Sling with Dolphins Grace effect #12
Fixed momentum being kept if the player starts flying/swimming after using the Slime Sling
Fixed the player being able to keep momentum and continue bouncing endlessly below 1.5 blocks of fall distance by holding the jump key (with config to re-enable)
