Changes Made:
Previously a trigonometric method was used that assumed flat geometry to estimate the n-gon of a circle. This caused distortions at latitudes far from the equator.
The azimuthal equidistant projection is now used in
get_circle_coordsto provide points on the map that are at proportionally correct distances from the centre point no matter where it is on the map.
