Fix contestation period conversion in smoke test

[ch1bo]

We had been truncating the block time even after taking the 10 multiple. Preview network uses 0.05s and this * 10 does truncate to 0s.

Adds a fromDiffTime smart constructor to avoid usage of UnsafeContestationPeriod in this instance at least.

No changelog entry as this got broken since last release.

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.
