Improve Performance Speed of Generating Report

[Justintime50]

Pip Tree takes awhile to run, this is mostly due to the pip show <package> command taking about a half second for each package. This can very quickly add up.

Look into performance gains with Pip Tree by optimizing the code itself and also consider adding concurrently calling each command, appending each to the list, and at the end, sort the list by package name.
