Support for webmshare and catbox albums

I was wondering if it would be possible add support for these.

I think it's much more convenient to use a userscript for such type sites
(It's that I do. Well, probably I need to publish my userscripts, but I need to rewrite them a bit).

However, the support of it in gallery-dl makes sense:

• When you have a bulk of URLs.
• It's not possible to use a userscript with an archive attachment, since the browser just download it and I can't run a userscript on web page to download it with the required filename.
• It's trivial to implement.

There's also uploadir.

While these sites aren't gallery, many animators often share download links in comments/descriptions to these sites, either due to file limits or content restrictions on the sites they use to build their galleries.

I capture the descriptions with postprocessors and then later pass the links to other downloaders, but gallery-dl can already parse for some external links on some sites such as deviantart and furaffinity.

You can't download all external links as child instances of a process, it'd be a rabbit hole, but for direct links such as these, I figure you could make permission.

The similar sites: uploadir.com (it uses filename in content-disposition), 3dx.pw, kyot.me, lewd.cat, i.gyazo.com, cdn.discordapp.com, media.discordapp.net, a.pomf.se (https://web.archive.org/web/1/${url})
