Genesis config

[JoshOrndorff]

The current genesis config could be a little nicer.

https://github.com/Off-Narrative-Labs/Tuxedo/blob/7f1dabe37ce8621deb9df47d102ea775bbe2f763/frameless-runtime/src/lib.rs#L107-L109

In the UTXO model the state is (basically) just the utxo set. In this sense, the current design is perfect with its single Vec of outputs. But there are still a few things that may be desired.

1. Including a money in the default genesis config is unusual. The default should be empty and the output that goes to SHAWN_PUB_KEY should be expressed in one or more of the specs in chain_spec.rs.
2. We should figure out the best-practice way of expressing the genesis utxo set in the chain_spec.rs file and provide helper functions or builder pattern or something if necessary. Off the top of my head, maybe something like.

let genesis_utxo_set = vec![
  (Coin(5), SigCheck(ALICE_PUB_KEY)).into(),
  (Amoeba{ generation: 5, ..Default::default() }, UpForGrabs).into()
];
