Version 1.2.2-1.6.2 for 1.20.1

Prices File Format: Prices are now saved as NBT instead of JSON, old files will be converted and then deleted.
- What This Means: This should fix many NBT issues in the admin shop including the inability to save tools and such!
- File Editing: To view or edit the file, consider using a program like NBTExplorer.
- Backups: Consider backing up your old prices file in case the mod fails to convert the file. This shouldn't be necessary but can't hurt.
JEI Integration: Locked prices are now hidden from JEI.

Sizing Issues: Scrollbar elements are now sized correctly when the scrollbar is visible.
Undraggable Scrollbars: Scrollbars in the admin shop are now draggable.
Clicking Off-Screen Elements: You can no longer click scrollbar elements that are off-screen.
- What This Means: This should fix issues with not being able to press the purchase button when not scrolled all the way down.
Exporting Crash: Fixed issues with exporting items when there is more than one item stack.
Empty Purchase Crash (1.21.1): Empty purchases are now ignored to avoid crashes.
