Allow commands to test player inventory slots against data pack tags

The idea behind this suggestion is to allow a way for commands to test the contents of a slot in the player's inventory against a data pack tag, whether that's through an existing construct, like the "tag" portion of an item's NBT data, or through some entirely new method.

This would be similar in functionality to using a tag in a custom recipe to specify several different items that can be interchanged in the recipe. In the case of custom recipes, this allows data pack authors to use only one recipe instead of requiring them to write one recipe for each item in the tag.

When applied to player inventory slots, this would basically allow data pack authors to check for any one of a group of items, as defined by a data pack tag, without requiring one command for each item test.

  That's simply not how NBT works; it has to match exactly how it's saved, and it's not saved with the tag.

  Dhranios Thanks for the feedback. I understand that's not how things work right now--that's why I made this suggestion--but I can see now how this might be too much of a change to how NBT data is fundamentally used to really be feasible. The basic idea behind my suggestion was more to give us a way to check inventory slots against data pack tags, similar to how custom recipes can be defined with a tag to allow a group of items to be interchanged in one ingredient slot without requiring a recipe to be defined for each item, so anything that could accomplish that would fulfill the intent of this suggestion. I'm going to update my suggestion to more clearly reflect that idea.

  I would love for this to be included, as I'd like a way to check if a player has any tool in their inventory, and then run a command. It seems to me like it should be in the game already.
