Partial compression detection false-positive leads to wrong compressed format

Description

I suspect Ouch is detecting extensions like .tar.zst as part of .tar.gz and skipping the .gz compression part.

Current Behavior

When trying to compress an archive like this:

$ ouch c less.pkg.tar.zst less.tar.gz

It outputs:

[INFO] Partial compression detected. Compressing less-1-590.pkg.tar.zst into less.tar.gzPartial compression detected. Compressing less-1-590.pkg.tar.zst into less.tar.gz

And then, trying to decompress it, Ouch warns:

~/ouch ouch d less.tar.gz
[WARNING] The file extension: `gz` differ from the detected extension: `tar`
Do you want to decompress 'less.tar.gz'? [Y/n] 

Expected Behavior

Partial compression should not trigger in this scenario, and the archive should be formated with .tar.gz.
