Thoughts on switching our archive compression method

[Vincent Habchi]

Ryan,

> Maybe, but if we could use something built into macOS, like xz on 10.9 and later, then we wouldn't need to bundle yet another third-party project (the decompression program) into MacPorts base.

Sure, but if the ultimate goal is to reduce disk size and bandwidth, then it can be worth bundling a decompression utility with the base, given it yields better compression ratios. Also, if that utility compiles on MacOS < 10.9, that means we could have a single compression process for all the OS versions we package for.
