Add option to set image icon to file's self

[Alex Stout]

Thanks for this utility by the way. I was taken back by the deprecation of sips -i in macOS 10.13 and found your utility to fulfill my needs.

That said I would like to suggest a minor improvement. Either add another command like:

fileicon setself icon.png

OR modify the set command to allow a single argument. The default behavior of a single parameter would be just like sips -i where the image file icon is set to the content of the image file itself. i.e.

fileicon set icon.png

Honestly this is just out of sheer laziness. I'd prefer not to provide the same path twice ;).

Your laziness is my command 😉

I've just published v0.2.2 to the npm registry, which now does what you want.
