Indefinite length decoding support for Bytes

[lehins]

It turns out that in all places where we decode ByteString, ShortByteString or ByteArray we do not support indefinite length decoding, which is not in accordance to the CDDL specification that we provide.

We need to change these instances to start accepting indefinite length encoding starting with protocol version 12:

cardano-ledger/libs/cardano-ledger-binary/src/Cardano/Ledger/Binary/Decoding/DecCBOR.hs

Lines 348 to 368 in 8aac6e0

	instance DecCBOR BSL.ByteString where
	decCBOR = BSL.fromStrict <$> decCBOR
	{-# INLINE decCBOR #-}
	instance DecCBOR ShortByteString where
	decCBOR = do
	BA (Prim.ByteArray ba) <- decodeByteArray
	return $ SBS ba
	{-# INLINE decCBOR #-}
	instance DecCBOR ByteArray where
	decCBOR = decodeByteArray
	{-# INLINE decCBOR #-}
	instance DecCBOR Prim.ByteArray where
	decCBOR = unBA <$> decodeByteArray
	{-# INLINE decCBOR #-}
	instance DecCBOR SlicedByteArray where
	decCBOR = fromByteArray . unBA <$> decodeByteArray
	{-# INLINE decCBOR #-}

We also need to make sure that none of the types that ByteString, ShortByteString or ByteArray rely on default implementation in decCBOR, which uses FromCBOR instance that will not have this fixed.
