allow processing the sieve locations for bucket-sieved primes with respect to selected congruence classes mod 2. For the moment it's essentially useless, because nothing is done for other sieving spots, and the (i,j) coordinates are not scaled in the end. But it's at least a first move.

There's a #define, which currently _activates_ the code.
