Extend API to build transactions for Hydra

[szg251]

Subtasks

• set ex budget to maximum for all transactions (no Ogmios evaluation needed)
• set tx fee to 0 for all transactions
• implement HydraClient with ChainQuery and Submitter trait
  • queryUtxos will parse the whole snapshot (suboptimal, but good enough for the first iteration)
  • evaluateTx always returns error (should not be used)
  • read protocolParameters from a file
  • getNetwork should be a configuration
  • querySystemStart should be queried from Hydra once we have that optino, but currently configuration is good
  • queryEraSummaries static configuration value
  • queryTip should be able to parse from the snapshot

Hey @szg251 Does any of the tasks relating to the Hydra case include the deployment of the protocol and the head? Similar to the nixos thing we have now?
