Barrage board game enhancements + Nile Affair Expansion update

Edit 27. 9. 2023: I've bought Nile Affair Expansion and updated slade_the_dragon's insert for it:

• New resources box which also stores 24 Irrigation and 5 Irrigation Scoring tiles.

• Adjusted Preparing box where you can put new Bonus, Objective, Private Building - Pump Station and 8 Headstream tiles.

• New Private Contract and External Work tiles fit into original boxes.

Everything still fits to the original box even with the new map.

-----------------------------------

I have printed slade_the_dragon's insert for Barrage ( https://www.thingiverse.com/thing:4865959 ) and add some customizations:

• Cover for resources (for possible vertical storage)

• Cover for water drops (for possible vertical storage)

• Custom wheel arms. I did not like any existing because I'm used to rotate the wheel by end of arms

• Cover for special tiles (for possible vertical storage) - added 12. 4. 2023

Water drops are designed by JMPlus ( https://www.thingiverse.com/thing:3819024 ), printed in vase mode with Fillamentum PLA Crystal Clear Iceland Blue filament.
