Add support for more archive formats

[Gabriel]

Dear David,

Could you be so kind to add support for more archive formats?

At present I have to use Find function of WinRAR to look inside *.(tar).xz, *.(tar).zst, etc.

[void]

Moved from Is it possible to search for content within an archive file.

I have put .tar, .xz and .zst formats on my TODO list.

Thank you for the suggestion.
