## opengraph
discord and social-media embeds
can be enabled globally with `--og` or per-volume with volflag `og`
note that this disables hotlinking because the opengraph spec demands it; to sneak past this intentional limitation, you can enable opengraph selectively by user-agent, for example `--og-ua '(Discord|Twitter|Slack)bot'` (or volflag `og_ua`)
you can also hotlink files regardless by appending `?raw` to the url
if you want to entirely replace the copyparty response with your own jinja2 template, give the template filepath to `--og-tpl` or volflag `og_tpl` (all members of `HttpCli` are available through the `this` object)
because discord (and maybe others) strip query args such as `?raw`, opengraph is incompatible with filekeys and dirkeys
