Convert coordinates to Pixels

[Genysys]

Problem

We currently represent regions as uint256 , which leads to a loss of precision in storing GPS.

Solution

Store the regions as an nested struct , Pixel.

    struct Coordinate {
        uint256 lat;
        uint256 long;
    }

    struct Pixel {
        Coordinate a;
        Coordinate b;
        Coordinate c;
        Coordinate d;
    }

This will change the mint function signature to :

 function mint(Pixel[] memory region, uint256 rioAmount)

Acceptance Criteria

• All tests pass.

Sample Pixel

[[3026662684114933,503277661947526],[30271123442967948,503277661947526],[30271123442967948,5033046415584378],[3026662684114933,5033046415584378]]
