Tests whether a point is inside a polygon using the ray casting algorithm.
The polygon is represented as an array of [lon, lat] coordinate pairs
forming a closed ring (first and last points are identical).
Parameters
x: number
Longitude of the test point in decimal degrees.
y: number
Latitude of the test point in decimal degrees.
ring: number[][]
Polygon exterior ring as [lon, lat] coordinate pairs.
Returns boolean
True if the point is inside or on the boundary of the polygon.
