Remove hydra-explorer from this repo

[noonio]

This removes the hydra-explorer from this repo; and needs to be merged in combination with cardano-scaling/hydra-explorer#5.

Note that there was one set of tests in the hydra-cluster tool that depended on the explorer; I've had to then remove those here, but am not yet sure if I can get them to work over on the other side.

Todo:

• Update changelog
• Check for references in the docs
• ???

Transaction 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 benchmark results produced by Hydra's continuous integration (CI) system from the latest master code.

Please note that these results are approximate as they are currently produced from limited cloud VMs and not controlled hardware. Rather than focusing on the absolute results, the emphasis should be on relative results, such as how the timings for a scenario evolve as the code changes.
