p7zip

[laffer1]

p7zip is no longer maintained from the original sourceforge site. A third party has started working on it on github. https://github.com/jinfeihan57/p7zip

Investigate migrating our port over to that release as it fixes multiple security issues and adds a lot of new compression options. (zstd, etc)

if we don't do this and we do get 7-zip ported, just drop the port.

We ported 7-zip to 3.x and higher but it does not work with 2.x. This may still be needed until 2.x is EOL
