[FR] - Pretty printer for Tx

[locallycompact]

We have a simple pretty printer for Tx in hydra.

https://github.com/cardano-scaling/hydra/blob/2b20fb7b53b3df37ae9607b7acbd18627f260d6e/hydra-cardano-api/src/Hydra/Cardano/Api/Pretty.hs

We want to factor this out to its own library, perhaps this could be ported to cardano-api under a sublibrary such as cardano-api:pretty. Our printer just has a Tx -> String interface, but we could also leverage something else like formatting.

Would this go in this repository? Or somewhere else.

@Jimbo4350 Is this something you would have an opinion on?

Nice! That would be useful to have. Does it have to a sublibrary? This code is pretty self contained so I think it can be simply a module in cardano-api.

Yes, sorry I failed to notice all the already existing render functions throughout this codebase so I can just put this somewhere that feels consistent.
