Armor Speed

### From version 2.0.0 and onwards, only Fabric will be supported. My system has issues with Forge and Neoforge, which prevents testing on most versions. --- Changes players' movement speed based on the armor they are wearing and if they are holding a shield. Scales with the total armor points. --- For the time being, the config is not able to be edited in game. To change values, you must edit the file using Notepad or something similar. --- If you want to exclude an armor item from slowing the player, add it to the "armorspeed:weightless" tag in a datapack.
