create RandomCoordinate command line version

This tool did not implement JFrame elements in the script class so the
CLI implementation did not need to create an src/window_interface/*/
RandomCoordinateOutput class. As a result, no need to create an Output
window class so fewer edits to be made:

window_interface/*Window
	-adjust output argument when initializing script class to be
		full filename and not just directory
script/*
	-use output as filename rather than directory name
cli/*
	-call appropriate script class
	-write up picocli parsing objects
	-write up validateInput() method to check inputs and write
		messages for the user
