you can also hotlink files regardless by appending `?raw` to the url
NOTE: because discord (and maybe others) strip query args such as `?raw` in opengraph tags, any links which require a filekey or dirkey will not work
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)

volflag `dks` lets people enter subfolders as well, and also enables download-as-zip/tar
if you enable dirkeys, it is probably a good idea to enable filekeys too, otherwise it will be impossible to hotlink files from a folder which was accessed using a dirkey
dirkeys are generated based on another salt (`--dk-salt`) + filesystem-path and have a few limitations:
* the key does not change if the contents of the folder is modified
* if you need a new dirkey, either change the salt or rename the folder
