"iTunes Media Library.xml" => "iTunes Music Library.xml" [Sierra]

[alundiak]

In readme.md file there is usage of

"iTunes Media Library.xml"

But on MacOS Sierra after iTunes did at least one export, it creates files:

"iTunes Music Library.xml"

diff: Media vs. Music.

I think, it somehow should be reflected in readme file. Maybe in MacOS, there is variable like $ITUNES_LIBRARY_FILE or similar, we could then have universal approach for all OSs.
