Inventors of the South Tigris+Expansion

Added an STL for the expansion content.  This is just a simple box container that fits in the gap above the other tiles next to the cards.  I then trimmed the score sheets so they fit above the new player board (these are layered 4 deep side by side).  This causes a slight cover lift but still everything fits in one box.

Inventors of the South Tigris - Storage insert holds sleeved cards (may need trimming to fit).
