NSImage to JPEG file?

I have a background macOS daemon process (aka Foundation-based "command line
tool") that needs to write out a JPEG file to local disk. The image resides in
an NSImage object (or alternatively, an NSData of raw RGB image data).

Short of resorting to something like libjpeg, what is the ObjC way to do this?
