Po-util: The Ultimate Local Particle Experience for Linux and macOS

UPDATE:

This script can now also patch the system firmware to change the DFU baud rate speed from 14400 to 19200, meaning that triggering DFU mode on a Photon or Electron without pressing the SETUP and RESET buttons can now be done on Linux.

The flash command now puts the device into DFU and automatically compiles and uploads new firmware to it, allowing quicker development.

See 2.0 Installation instructions in a post below.
