This is a follow-up to #429, and also adds š¾ā multiplication and exponentiation to zkalc (#425).
Surprisingly the slowdown for constant-time š¾ā exponentiation is only ~10% on BLS12-381 (138Āµs vs 153Āµs)
This is about 3x slower than G1 vartime and 2.5x than G1 constant-time
And 1.5x / 1.2x slower than G2 vartime/constant-time
