Retest more costly move ordering schemes after more aggressive late move pruning

[heofthetea]

A lot of "more aggressive" ordering heuristics did not gain:

• storing 2 killer moves
• Relative History Heuristics (although that seems to not be relevant in practice)
• Additional PieceTo History Heuristics (exists in viridithas)

It may be worth trying to re-add them after some more aggressive pruning has been implemented to see whether that increases their effectiveness.
