* Make the project build with Microsoft's broken C compiler.Sebastiano Tronto2026-04-061-11/+10
| | | | | | | | | | | | | MSVC is not fully C11-compliant, even when compiling with /std:c11. Some changes were needed to make the codebase compatible. Notably, the notation a[static N] and a[n] for function parameters of array type is not supported, so that had to be hidden behind a macro. Atomic types are also an experimental feature, apparently, but at least they work with the correct compiler flag. One thing that MSVC does well, however, is warning on integer conversions on /W4 level. I am not sure if Clang and GCC have something similar, so I took this chance to fix some of these.

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.
