Try lookup tables for `orientation_mod` calculations #24

Closed lgarron closed 10 months ago

lgarron commented 10 months ago

I tried a lookup table for the no_orientation_mod case in ac259e3d945056d8257c166bc572f75acf1e32b1 but reverted it in 1b8a6e510ac57e556b469f1e1d7b612b12c3e1be because I couldn't measure a speed gain. (It seemed to be under 1M moves/s, which is the normal variability range for cargo run --release --example test-cpp_port.)

However, the default logic is now more complex:

It might benefit from its own lookup table, probably also stored in PackedKPuzzleOrbitInfo.
