Add support for compressed files

[AlexGustafsson]

Discord only allows small files if you're not a Nitro user.

One workaround is to support files compressed using gunzip or something else.

An example solution, which worked for me to continue testing this tool. But it's obviously too limited to merge as is, hence no PR.
