feat: add sink for commanders to write output/read input (#232) to write output, you would usually just use the print builtin since commanders are just lua custom commands but this does not consider the fact of pipes or other shell operators being used to redirect or whatever. this adds readable/writable "sinks" which is a type for input or output and is currently only used for commanders but can be used for other hilbish things in the future 2023-01-20 23:07:42 +00:00			`commander.register('fg', function(_, sinks)`
