[Feature Request] support for new Tachiyomi .tachibk backup format

[watashibeme]

What feature should be added to Tachidesk?

It seems that preview-version of tachiyomi is utilizing a new format for backup function with .tachibk extension, causing incompatibility for someone like me who has been using preview versions for quite some time( probably others too)

Why/Project's Benefit/Existing Problem

it's possible that this new .tachibk could replace the current .proto.gz(proto) backup format in near feature . adopting it early on could be great, although I still don't know how it can be opened, it would be nice to hear other people opinion as well, thanks!

The server should be able to handle the file, I don't think WebUI or other clients are importing it though.

I see.

[schroda]

looks like the webUI requires the backup to end with proto.gz

[watashibeme]

ok. so I confirmed that a simple rename of backup file's extension to proto.gz does the trick.

Should I close this now?

[schroda]

we should transfer it to the webUI repo @Syer10 , I'll close it then once it's fixed
