  • Code to wait for a pull to happen was wrong -- it only waited in one direction, and it waited essentially forever. Not a good idea anyway, since the pin might be tied firmly to one value or the other. Instead, add a brief delay after setting all pulls.
  • Make sure RTC is powered up during sleep.
  • Unrelated corrections. to Metro ESP32-S2 debug UART pins.

no testing performed but the basic change makes sense. waiting forever for a pin to reach a particular status doesn't seem right. 50ms should be generous for almost any RC constant of a pulled I/O pin.

I will merge this now in prep for a beta.4 fairly soon. @kattni you can test at your leisure.
