Remove unused functions

[locallycompact]

Every function that is not used in this codebase has been removed, with the few exceptions listed in the weeder roots.

A weeder check has been added to ensure no unused functions sneak back in.

Anything that is actually really needed can either be readded from history, or upstreamed to a library or form a new library so that it can be discovered in hoogle.

• 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.
