Genesis config file parsing

[scarmuega]

We want to be able to load genesis config files (byron, shelley, alonzo, etc) as defined by the Haskell node implementation in order to use those values in downstream components.

DoD:

• we can load & parse Byron genesis json files into structs
• we can load & parse Shelley genesis json files into structs
• we can load & parse Alonzo genesis json files into structs
• we can load & parse Conway? genesis json files into structs

Did I see this being started somewhere already? Or am I confused?

We had #59 but I ended up constraining the scope to just Byron genesis because I needed a way to generate those initial UTxOs. Added this issue to keep track of work for the remaining config files.

There are still a few issues with genesis config parsing that affects the ability for downstream tools (ex: Dolos) to work with tools like yaci-devkit

You can find the result of the investigation by us & the devkit team here: bloxbean/yaci-devkit#86 (comment)

Notably, the issues are:

• shelley initialFunds wrong type (also, I think the contents of this field are ignored in general)
• shelley pools not supported
• alzono PlutusV1 missing supported format
• alzono PlutusV2 not supported
• alonzo executionPrices wrong type
• conway constitution wrong type
