feat(Equipment): Handle DFS4 Tier Sets

- Create "DFS4" sub-table in TierSets
- Create a translation table in Player:HasTier function
--- Table holds which tier set is used on the DFS4 tier set
--- If we're checking for a set bonus that's now on the DFS4 set, return true if we have either the DFS4 pieces or the original tier's pieces
--- This is because simc is doing similar, rather than creating a T32
--- Example: If the Arms profile calls Player:HasTier(29, 2), it will return true with 2 pieces of old T29 or DFS4
