Five Duration Swing

For all the maniacs (me) who want to use a faster hand swing mining animation without wanting to install mods.

This datapack works by conditionally applying haste 1 effect on the player, then scale back the mining and attack speed buff.

WARNING: BE CAUTIOUS WHEN PUTTING THIS ON A SERVER, AS THIS DATAPACK RUNS A PREDICATE CHECK EVERY TICK AND CAN POTENTIALLY HURT PERFORMANCE.

Datapack versions below 82 might receive errors from the json versioning format change on 82+.
