If the archive has only one directory in the root, then unpack it as OutputDir

For example, in Go distributions in the "tar.gz" archive there is only one directory named go and the unpacking gets the path outputDir/go, but I would like only outputDir

Can you tell me more about the problem this solution will solve? Then I'll share and tell you about the problem this solution causes.

I want to unpack, for example, a Go distribution into the go-1.22.5 directory.

Currently I have to do the following:

1. Unpack the archive into a temporary directory
2. Get the first and only go directory from the temporary directory
3. Move the resulting directory to go-1.22.5
4. Delete empty temporary directory

What I would really like is some kind of equivalent of --strip-components=1 from tar that I could pass through xtractr.XFile

Doesn't seem like an unreasonable request. I'll look into this. As for the problem this would create that I alluded to, it's probably insignificant in this context, but if you extract two go distribution versions into the same output folder, you'll have a mess.

1. unpacking a version of Go - an example of a public archive that was easy to demonstrate
2. I don’t extract Go into one directory - I’m just writing an analogue of the asdf utility, only in Go :)
