Add a function that returns the time remaining before triggering for a given pool and alarm id
It uses difference between an alarm register and the timerawl register. (see RP2040 datasheet chapter 4.6.3)
It also check that the alarm for which we're asking the remaining time is the actual one running on the hardware timer (and not in the alarm pool)
