LevelChanges reported when in fact level stays the same

[andrewdavidmackenzie]

I have tracked this down to rppal and reported an issue there:

golemparts/rppal#149

I will try to filter out in pi_hw.rs but it's not easy due to the bounds on the callback called from the interrupt.

Seems this is coming from linux/drivers - and so very hard to fix. I'll leave it here for now, but not for next release.

Upgrade to new API mentioned here golemparts/rppal#149 (comment)

after next release, then check it makes a difference, or we can use that to filter out unecessary events.

Move to v2 of rppal

[andrewdavidmackenzie]

for 0.4.0

Waiting for a new release of rppal
