Main build failing with 'RuntimeWarning: overflow encountered in scalar subtract'

Looks like it may be due to stricter checks in NumPy 2.0.0.

tau_p = np.uint8(0), lambda_p = np.float64(0.0), ploidy_p = np.uint64(2)
kinship_pp = 0.0, tau_q = np.uint8(2), lambda_q = np.float64(0.167)
ploidy_q = np.uint64(4), kinship_qq = np.float64(0.307798800184587)
kinship_pq = 0.0
