Add DO:X Cross map

[RedRafe]

Adds a X Cross map (very similar to the 3Way T shaped one).
Each arm has a main ore among iron, copper, coal, stone.
Map is rotated 45 degrees

[RedRafe]

For reference, main_ores_builder is same of the 3-way (T cross) just without the tip of one arm cropped, and rotated 45 degs. Same for the scenario code, while ore config is default ore config, + stone not commented out

I don't think the map gen is working, I just get this:

I don't get any errors in Debug mode. Do you know what is going on?

My bad, I messed up the require in my map selection.

Looks good. Stone might be a little high but we can adjust after a playthrough.
