Generates a test instance with a bipartite graph where there are {@code lhsSize} elements in
one set of vertices (which we call the LHS) and {@code rhsSize} elements in the other (the
RHS) and whether or not each of the {@code lhsSize * rhsSize} possible edges is included or
not according to whether one of the first {@code lhsSize * rhsSize} bits of {@code bits} is
set or not.
