nRF5x: Add support for negating pins in software (eg. buttons/LEDs)
Add `E.setFlags({unsyncFiles:1}` which doesn't sync the file to the SD card after each write - it's *much* faster
Filesystem API now uses flat strings (avoiding the 512 byte copy for each call)
Increase default internal SD card bitrate to 4MHz (from 100k)
1v94 : Allow Espruino boards to reset straight out of the DFU Bootloader
