TODO make this a bimap Text - Vector. Compare performance when printing backtracking results. (Do this after the Builder-based backtracking is online)

btiBimap :: IORef (Bimap Text Int)

btiBimapAdd :: Text -> Int

btiBimapLookupInt :: Int -> Text

Lookup the InternedMultiChar based on an Int key. Unsafe totality assumption.
