coordinateForPoint give wrong Point. about sktiled HOT 2 OPEN

Looks like I need to rework the TiledLayerObject.coordinateForPoint method.

The reason for this is because of the difference in coordinate systems between SpriteKit and Tiled. Internally, the conversion between screen points & tile coordinate is happening in Tiled's coordinate space, and converted by the coordinateForPoint & pointForCoordinate methods.

If the point (in SpriteKit coordinate space) is (216.0, -24.0), the floor operation incorrectly returns 2 because floor(-24.0 / 16.0) returns -2 and floor(24.0 / 16.0) returns 1.

Modifying this code will give you the correct result:

    open func coordinateForPoint(_ point: CGPoint) -> CGPoint {
        let coordinate = screenToTileCoords(point.invertedY)
        return floor(point: coordinate)
    }

I'll run a few tests to make sure everything checks out, and push up a fix.

for now it works. thanks for the awesome framework!
Edit: invertedY is not good. if pixelY is 24 it would be -24 and we have the same problem again.
if (pixelY < 0) {pixelY += 16} fixes my Problem
