Add tools executable to generate Hydra key pair

[ghost]

This is related to #189: Trying to spin-up a node myself I realised there wasn't any easy way to generate those keys so I wrote this small tool.

Transactions Costs

Sizes and execution budgets for Hydra protocol transactions. Note that unlisted parameters are currently using arbitrary values and results are not fully deterministic and comparable to previous runs.

Cost of Commit Transaction

Currently only one UTxO per commit allowed (this is about to change soon)

Cost of Abort Transaction

Some variation because of random mixture of still initial and already committed outputs.

Parties	Tx size	% max Mem	% max CPU	Min fee ₳
1	13703	25.73	10.91	1.04
2	13605	34.02	14.28	1.13

Cost of FanOut Transaction

Involves spending head output and burning head tokens. Uses ada-only UTxO for better comparability.

UTxO	Tx size	% max Mem	% max CPU	Min fee ₳
1	13484	10.26	4.46	0.86
2	13584	12.16	5.49	0.89

Nice. Slight YAGNI: What if we never need other things than keygen? Naming the executable what you have as subcommand would be more on point, for now.

[ch1bo]

Forgot something:

• Please refer to this in the docs, section https://hydra.family/head-protocol/docs/getting-started/quickstart#hydra-keys
• Add a changelog entry about this

[ghost]

Yeah, I agree with the YAGNI :) What about moving the publish-scripts command there (later, in another PR)?

I have added another tiny command to output the marker datum hash, something I have been needing while experimenting with deploying hydraw.

Still missing:

• Please refer to this in the docs, section https://hydra.family/head-protocol/docs/getting-started/quickstart#hydra-keys
