Hashes

I added the hash functions for datum and script data.

I forgot to wrap the cost model inside language views (Costmdls):

Will update that

Awesome. I'm still struggeling a little bit with the hash_script_data function. Was yet not able to reproduce the same hash in the serialization-lib as in the cardano-cli, although I feel according to the specs it looks correct. The concatenation of redeemers, datums and cost models.
