URxvt has support for specifying alpha in OSC color sequences, either using a [alphapercent] prefix, e.g. \E]11;[50]..., or as an rgba sequence (instead of an rgb sequence): \E]11;rgba:rrrr/gggg/bbbb/aaaa.

Since foot has support for background alpha, we should implement this. It is used by e.g. pywal to set the alpha (using the -a <alpha> command line option).
