• clip arguments in .bytereverse() instead of raising IndexError
• remove ssize_richcompare() in favor of Py_RETURN_RICHCOMPARE macro

• fix random_p() silently producing all-zero bitarrays for small n when p=float("nan")
• improve integer argument handling in util.random_k(), util.gen_primes(), util.pprint() and util.int2ba()
• add python_requires >= 3.7 to package metadata
• improve testing - use more of unittest's functionality
