Elder Sign - Insert for base game + expansions

Based on Elder Sign - Insert for base game + expansions by parax , this splits the main insert into two pieces that fit a P1S plate, along with removing the containment section that the card and token trays fit into as they'll be held in by the box. Removed portions of the bottom underneath card sections to reduce filament usage, and rounded the corners on the dividers of the card tray to do the same. The suggested ribbon underneath the card tray will no longer work (the bottom section here was removed) but with the two trays now just contained by the box, they are easier to remove.
