So... waking up once per second turns out to be a dumb idea because it
regresses the stop watch and HRS tools (which now also only wake up once
per second).
Undo this change but sprinkle a few more micropython.native decorations
on methods used on the wakeup path to minimise power.

This is useful for devices that do not have touchscreens. It can be used
to cycle through the quick ring and to check out notifications.

The K9 is similar to the PineTime and P8 devices but does not appear
to use the CST[78]16 touch screen controllers. At present the protocol
is not known (readfrom yields all zeros, readfrom_mem provokes an
exception) so we have a hugely limited interface consisting of the side
button and the touchscreen interrupts (in other words we can treat the
touchscreen like a second button).
Works suprisingly well considering...
