Windows counterpart for the pico autoflash script for mac.
Essentially functions the same way just that the script is much simpler.

The script is run in command line like this 'python pico-autoflash-windows.py pathtofile.u2f -d F:'

• Path to file is the location of the u2f file and -d is an optional argument for the drive letter (default is D:)

Steps to use:

1. Run the command in command line and it will say its waiting for the pico
2. Take the pico and press and hold the 'BOOTSEL' button
3. Plug in the pico to the computer with your USB cable
4. Wait for the message 'Firmware installed - Rebooting Pico'
5. Remove the pico
6. Select the next pico and go back to step 2
7. To exit the script press 'Ctrl+C'

Fixed a typo (time.sleep(5'') line 37 should not have the apostrophes
