JER parses loot tables before tags & other datapack elements are completed

[Tslat]

Title.

JER parses loot tables a little early, which basically breaks the entire mod when any other mod uses tags or something similar in their loot tables (which happens fairly frequently). Is there a reason the loot tables can't be parsed after datapacks are completed?

To be more specific - any loot table that uses a function or condition that relies on tags will cause TagRegistry to throw an ISE at line 131: "Tag {} used before it was bound"

think this is the same as/very similar too #263 which has been tagged as enhancement and open for a while... I want this too though, damn
