Absolute Path Translation

I will try to put together a formal pull request, but in the meantime, here is the base issue it would solve.

If your media filenames are the same, but you've mounted your media in a different location, then the absolute paths will differ, and this script will fail for all items.

For example, my Plex instance has my media mounted at /media, while Jellyfin meets my newer standards and has it mounted at /mnt/media.

Ideally, this would be fixed with a command-line argument that could specify pairs of translations, e.g., --translate src:dst or, in my case, `--translate "/media:/mnt/media."

In the meantime, here are the modifications I made to the script to do exactly the above, which users can implement or form the basis for that CLI feature.
