Description
Describe the bug
test_pwm_output_device_alt_values fails with the latest version of micropython v1.20.0-38-g1b980c9db
Previously micropython PWM.duty_u16 device would return 1 less than the duty factor when "on", if the duty factor was less than the maximum of 65535./
See this comment https://github.com/RaspberryPiFoundation/picozero/blob/master/tests/test_picozero.py#L182
This is no longer the case.
