Purpose of change (The Why)

Lake content is hard to access, and people have been exploiting prospecting pick mechanics to reveal it.

Describe the solution (The How)

Add the long-awaited sonar item & vehicle part. This can be used to scan 7 tiles around the player, and 5 deep. Using this new item, the player can explore and plan underwater expeditions much easier without wasting resources. They can be found either at freshwater research stations, or found already installed in fishing & scuba boats.

Describe alternatives you've considered

Implementing it in C++? We needed the bindings to reveal stuff on the overmap, anyways, so I figured this would be a good usage & example for them.

Unhardcoding the list of underwater location patterns? Would likely require a flag for underwater locations, and wasn't sure of the best way to go about this, so gonna leave it as is for now.

Testing

Spawned in a fishing boat, used it to reveal the underwater terrain nearby.
