Fix failing cuddle test for Plutus data Constr.
Triggered by: ``` cabal run cardano-ledger-conway:test:tests -- --match "/Conway era-specific/CDDL/Huddle/Decoding fails when term is zapped/plutus_data: MemoBytes (PlutusData ConwayEra)/" --seed 1615161393 ``` The issue is that our list of allowed tags for the `Constr` data constructor of Plutus `Data` is not exhaustive enough. As per `PlutusCore.Data`, the allowed tags are 121-127, 1280-1400, and 102.
