Important test flag
test_delay_upper_bound: Default: False. If True, the test checks
the return value of stopWatch with upper bounds. If False, it
doesn’t check upper bounds. It checks lower bounds only.
Expand dependency version ranges for transformers and clock.
Loosen the test. Now it checks only lower bounds of the measured
delay, not upper bounds. This is because in some environments, it’s
difficult to ensure the upper bounds.
