Full rewrite and fixes

end result of this update? a SIGNIFICANTLY more stable and improved version of the mod. still just as basic though, features are planned

rewrote how nbt data is stored, emerging features are, pet can have only 1 owner, but an owner can have unlimited amounts of pets

split hanlder into scoped files. handler now only handles rules and interaction flowchart, planned features have proper placeholder files

rewrote accessor and mixin to remove old code

added debug prints and debug messages for now to help development

properly registered commands, fully functional

fully reworked handler file, proper flowchat and rules clearly defined, cannot double click anymore, cannot attempt to tame after claiming anymore

compeltly reworked tame logic, also includes particles in its own file
