fixes #49

cna-assignment-info-to-json.pl is splitting the url field using commas (so commas within a CSV file's field), which is inherently adventurous https://github.com/CVEProject/automation-working-group/blob/master/tools/cna-assignment-info-to-json.pl#L104, but more importantly, commas are valid URL characters https://tools.ietf.org/html/rfc3986#section-2, so the perl script could produce json files where one URL is incorrectly split into 2 ore more URLs. Suggest whitespace as the internal field separator since it's one of the few illegal characters.

I can confirm that this change fixes the problem, but I realize many other people may not be expecting this change so it may require some coordination.
