These numbers are taken from a snapshot of chainstate two weeks ago. We will want to change them periodically to run benchmarks that are relevant. For the final v3 tuning we will want to extrapolate values we expect a few months out. Merging temporary values to master is ugly but setting values in source is a nice lightweight mechanism for updating.

We added this benchmark for resetting the set of existing keys to better match the expected workloads on some filecoin state tree HAMTs, i.e. power.Claims.

It may make sense to extract this from this package so we can avoid perf dep in HAMT. Additionally I expect to tweak and use this for measuring AMT so decoupling might make logical sense.
