Simplify a LineString using the Ramer-Douglas-Peucker algorithm.
Input: a list of lat, lon coordinates, and an epsilon float (Try 1.0 to begin with, reducing by orders of magnitude)
Output: a simplified list of coordinates
Example:
simplify_coords([
[0.0, 0.0], [5.0, 4.0], [11.0, 5.5], [17.3, 3.2], [27.8, 0.1]],
1.0
)
Result: [[0.0, 0.0], [5.0, 4.0], [11.0, 5.5], [27.8, 0.1]]
