Context: EcPairing.yul#L1419

Description: According to the referenced papers value returned by finalExponentiation() is not A^((p^12 -1)/r) but A^(s*((p^12 -1)/r)) where s is not divisible by r.

Recommendation: Update doc comment and add context information why it's not a problem that the result is raised to the power of s = 2u (6u^2 + 3u + 1), where u is the curve seed.
