…re now implemented in LUTs instead of DSPs.
Separated factor multiplications from finall addition step, and made them to be per input byte.
Masking can be implemented by selecting which multiply results are used in addition step.
No need to adjust for negative numbers, because only the first 64 bits (LSB) of multiply results are used.
Half of the bits in Hyperscan fixed magic number are zero, giving another 2x efficiency in using LUTs.
