Red Cathedral: Contractors Simple Insert

I've printed the great [remixed insert](https://www.thingiverse.com/thing:6664568) for the base game by [skidaddle23](https://www.thingiverse.com/skidaddle23/designs) and wanted some trays in that style for the expansion.

But I didn't need space for every last resource or piece in the expansion, just for the Diamonds and the Contracts, which are in-game resources. I also wanted some trays for the Contractors in each of the four colors.

I just re-dimensioned the trays from the base game's insert to fit the box better.
