TriPoint Freezes After Short Power Cycle #5

If power is removed and re-applied within a period of 60 seconds, the TriPoint module will become unresponsive due to the Decawave chip not responding to any commands. This may be un-fixable with the current Decawave silicon.

This appears to be caused by TriPoint VCC staying above 100mV. When DW1000 is in deep sleep, it takes a long time for the 10uF decap to drain to below 100mV.
