Scan text found at remote source URLs found in HTML files

I think it would be good to provide license and copyright scans for source URLs present in `script` tags in a HTML page.
For example:
'''
script-tag src="http://ajax.googleapis.com/ajax/libs/jquery/1.10.2/jquery.min.js"script-tag
'''
It would be nice if `Scancode-toolkit` can scan the resource URL present above and mention them in the scan results.
