a defnull/pixelflut inspired binary framebuffer thingie
run the server, it'll listen on ipv6/::/udp/54321.
to draw a pixel, send a binary datagram formatted as:
byte: 01 | 02 | 03 | 04 | 05 | 06 | 07 | 08 | 09 | 10 | 11 | 12 | 13 | 14 | 15 | 16
meaning: magic | x | y | R | G | B | A
values: "BFPX" | uint32_t | uint8_t
of course as this runs over UDP, the datagram, and thus pixel, is never guaranteed to arrive.
