Commit Message

Marcus B Spencer June 5, 2024, 10:58 p.m. UTC 
farbfeld is an uncompressed image format that is a part of suckless
tools (https://tools.suckless.org).

Its documentation is available at https://tools.suckless.org/farbfeld.

Add support for this image format in avcodec and avformat, and update the image2
format accordingly.

Any special reason to favor MIT over LGPL2?

Anyway I see we have other instances of MIT licenses, but probably
would be simpler to use LGPL2 to simplify overall licensing.
