Apx accepts any text file when importing

[dajix350]

Apx allows you to import any text file (including completely empty ones) as a stack or pkgmanager. Since they do not have a name value, they create broken stacks and pkgmanagers which you cannot remove.

 ❯ apx pkgmanagers import -i test
 INFO  Imported package manager from ''.
 ❯ apx pkgmanagers list
 INFO  Found 1 package managers
