[REQ] Add support for extracting Debian packages (.deb)

[Bendodroid]

Is your feature request related to a problem? Please describe

I often work with .deb files and they just appear as the white-page-unkown-file-type-placeholder icon in the Finder.

Describe the solution you'd like

.deb files are just compressed archives with a well-defined layout. I would like to have a nice file icon when Keka is registered as the default uncompressor and for Keka to completely decompress .deb files so I can inspect if the file layout/contents are correct.

Describe alternatives you've considered

I use tools on the command line to achieve the desired effect, but double-clicking the file in the Finder and Keka decompressing all the nested archives in one go would save time.

What command line tools can work with them on macOS?

What command line tools can work with them on macOS?

I just use tar xf foo.deb, as macOS tar links against libarchive which can also decompress ar archives.
