Shelley genesis information

Note that this is needed only for a pure Shelley network, hence it being defined here rather than in its own module. In mainnet, Shelley will transition naturally from Byron, and thus will never have its own genesis information.

Some reasonable starting defaults for constructing a ShelleyGenesis.

You must override at least the following fields for this to be useful:

• sgSystemStart the time of the first block
• sgNetworkMagic to a suitable testnet or mainnet network magic number.
• sgGenDelegs to have some initial nodes
• sgInitialFunds to have any money in the system
• sgMaxLovelaceSupply must be at least the sum of the sgInitialFunds but more if you want to allow for rewards.

Some reasonable starting defaults for constructing a AlonzoGenesis. Based on https://github.com/IntersectMBO/cardano-node/blob/master/cardano-testnet/src/Testnet/Defaults.hs The era determines Plutus V2 cost model parameters: * Conway: 185 * <= Babbage: 175

Decode Alonzo genesis in an optionally era sensitive way.

Because the Plutus V2 cost model has changed between Babbage and Conway era, we need to know the era if we want to decde Alonzo Genesis with a cost model baked in. If the V2 cost model is present in genesis, you need to provide an era witness.

When an era witness is provided, for Plutus V2 model the function additionally: 1. Does extra cost model parameters name validation: Checks for mandatory 175 parameters if provided in a map form. 2. If >= Conway: adds defaults for new 10 parameters, if they were not provided (maxBound) 3. Removes extra parameters above the max count: Babbage - 175, Conway - 185.
