Speed up zero neopixel pulses.
SK6812 on 5v is pickier than WS2812 on 5v.

Hopefully fixes #1083.

Jeff Epler b0e33f6a11 atmel-samd: UART: allocate rx buffer in long-lived region
This is not strictly needed in order for #1056 to be resolved,
because the "make long-lived" machinery is unaware of this pointer.

However, as UARTs are assumed to be long-lived, this change is
beneficial because it moves the long-lived buffer into the upper
memory area with other long-lived objects, instead of remaining in
the low heap.

Scott Shawcroft 2fbab8067a Prevent freezing USB during high frequency PulseIn.
We now track the last time the background task ran and bail on the
PulseIn if it starves the background work. In practice, this
happens after the numbers from pulsein are no longer accurate.

This also adjusts interrupt priorities so most are the lowest level
except for the tick and USB interrupts.
