Merge the "solver-experiments" branch that I have been working on for

a few weeks. This include mainly three things:

1. Various tweaks for a total performance gain of around 30%.
2. Take into account symmetries and avoid repeated work. This
   required a re-work of the splitting into tasks before the solve.
3. Add a second fallback table (eoesep). This gives huge performance
   gains for particular scrambles (e.g. superflip).

After merging this commit, remove and re-generate all pruning tables.

Squashed commit of the following:
