B-Sieged insert

Insert to store the tokens and dice for the B-Sieged boardgame.
Very surprised at how little space exists for these in the main game, and suggest that to be honest, the storage for the figures really should be reorganised instead.

This works though, the three trays slot together so can be lifted out as one (with the convenient 'handle') and organises all the cards and tokens.
Compass, Enemy and Event cards can stay in the card tray and be drawn from it directly as needed.

I've actually modified the STL's since I printed it to improve the 'slot' - had to sand the originals a lot to get them to slot together properly so have adjusted these further (but not re-printed them myself yet) to save you having to do so. Also made the finger cutout on the card tray smaller to reduce risk of breaking the slot rail on that tray.
