Download (or option to download?) SVG versions of files on philomena and booru-on-rails

[Twi-Hard]

For SVG images gallery-dl only downloads the png version. I'd like it to download both versions. Nearly all of the SVG images on Twibooru don't have a PNG version so it doesn't download anything.

It'll now download .svg files for SVG posts (or the pre-rendered version depending on svg), but it can still only do one file per post at the moment.

Is this OK like this or would it be huge help if it could download multiple files / file formats per post at once?

It should be possible for me to generate the PNGs myself with a postprocessor so I think it's good how it is. Thanks for the help :)

Edit: Script is working :)
It can now make the PNGs higher resolution than the site does most of the time
