add new heuristic rc2bin (to be tested) to maxsat

Browse source 
The rc2bin heuristic is a hybrid of rc2 and binary maxres.
It follows the suggestion by Nina to use rc2 on large cores after a single maxres relaxation step; otherwise maxres (binary) on smaller cores. In the design space of possible hybrids, this variant chooses to always apply a single layer of maxres and then rc2 for large cores.
