Fix Conway support

[ch1bo]

• Seems like we fail to decode conway blocks when running the smoke tests on sanchonet. Converting transactions by re-encoding is maybe a more robust way forward.

• A successful smoke test with this version: https://github.com/input-output-hk/hydra/actions/runs/8046987024/job/21975334384

• Also fix hydra-chain-observer to handle conway blocks.

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.

• The minting policy hash is only usable for comparison. As the script is parameterized, the actual script is unique per Head.

End-To-End Benchmark Results

This page is intended to collect the latest end-to-end benchmarks results produced by Hydra's Continuous Integration system from the latest master code.

Please take those results with a grain of salt as they are currently produced from very limited cloud VMs and not controlled hardware. Instead of focusing on the absolute results, the emphasis should be on relative results, eg. how the timings for a scenario evolve as the code changes.
