* POV Display usermod this usermod adds a new effect called "POV Image". To get it to work: - read the README :) - upload a bmp image to the ESP filesystem using "/edit" url. - select "POV Image" effect. - set the filename (ie: "/myimage.bmp") as segment name. - rotate the segment at approximately 20 RPM. - enjoy the show! * improve file extension checks * improve README, remove PNGdec reference, clean usermod * restrain to esp32 platform + reduce memory footprint with malloc
