Repair Cost Remover

Massively improved lag on datapack as whole.

• Function to edit items in the player cursor now only fires if the item has any repair cost above 0, and only checks every 5 ticks instead of every tick.
• Inventory edit functions now ignores items that have repair cost of 0, removing all unneeded item processing.

Another fix, and after a full test, fully works now in survival gameplay.

EDIT: Apologies, this is also broken. Use 2.3

Quick fix to allow inventory functions to properly trigger repeatedly again

EDIT: This version has an error, use the 2.2 version.

Updated pack format with the newer format introduced in 1.21.9+

Still supports prior versions.

• Added dedicated support for 1.21.5
• Fixed an error that resulted in items sometimes not stacking with others arbitrarily.
