Expand description

Calculates the affine transformation right * left + imm8 inside the finite field GF(2^8). right is an 8x8 bit matrix, left and imm8 are bit vectors. If inverse is set, then the inverse transformation with respect to the reduction polynomial x^8 + x^4 + x^3 + x + 1 is performed instead.
