Count on alarm

[microdev1]

The api can look like:

pin_alarm = alarm.pin.PinAlarm()
alarm.count_on_alarm(pin_alarm)
triggered_counter = pin_alarm.count

This might render countio obsolete.

Please explain what you are trying to do. I wouldn't change countio at all.

I know of uses for countio where people are just counting pulses. The Espressif impl uses the PCNT peripheral, not interrupts (as you probably know already).

Closing due to other uses for countio.
