Support to use fixcdn.hyonsu.com as an alternative to cdn.discordapp.com on mahto.id

Feature Description

Uh, hiya. At the moment I'm using the matho.id link for quick display of the transcript file, but discord started to expire attachments including the file after 24 hours, so the old URL doesn't work, however I'm seeing that there's a service at fixcdn.hyonsu.com which should be a dropin alternative to the old cdn.discordapp.com link and seems to works fine so far in my testing. is it possible to add support for this in the future? Thank you for reading
