tests\util\test_byte_formatting.py should give results and be able to run on its own

[SolarDon]

In the test_short_to_bytes function should add: print("test_short_to_bytes") at the beginning and print(" PASSED") to the end of the function

Similarly for test_bytes_to_short(): add print("test_bytes_to_short") and print(" PASSED") to the end.

Finally at the end of the file we should have: if name == "main": test_bytes_to_short() test_short_to_bytes()
