Add option to output image URLs as used in Discord

[TheTechRobo]

Right now, some Discord CDN image URLs extracted have their max size by requesting size 4096. There should be an option to output the original ones extracted (and an option to output both). The trouble with that for many URLs is there can be multiple sizes requested depending on the view (e.g. avatar URLs have different sizes depending on where they're located, e.g. in the side view with the list of all the members there's a different size than beside the message).
