Arduboy Image Converter

This worked great!
I've been trying to connect an adafruit Huzzah Feather with a Wavepaper 7.5in e-ink/e-paper display. Tried a few other online image to hex array converters but this is the only one that worked for me.
Thank you!

Thank you for including the "no scaling" option, i went through converters for an hour and this is the only one that outputs proper 1 bit per pixel in hex, and doesn't pad, scale or reformat the result :)
