This creates a common safe mode mechanic that ports can share. As a result, the nRF52 now has safe mode support as well. The common safe mode adds a 700ms delay at startup where a reset during that window will cause a reset into safe mode. This window is designated by a yellow status pixel and flashing the single led three times. A couple NeoPixel fixes are included for the nRF52 as well. Fixes #1034. Fixes #990. Fixes #615.
