Custom Permissions

Starting with version 1.10.0 all permissions are moved to a datapack system. This allows to very easily add custom permissions. The directory for permissions is located under /data/<namespace>/claim_permissions. For some examples refer to https://github.com/Flemmli97/Flan/tree/1.20.1/common/src/generated/resources/data/flan/claim_permissions
Do note that without doing anything further simply having the permissions will not do anything. One way to utilize the custom permissions without coding it in is via the config e.g. with assigning items to them in customItemPermission.
