Implementation
Future<(Point2f center, double radius)> minEnclosingCircleAsync(VecPoint points) async =>
cvRunAsync2((callback) => cffi.MinEnclosingCircle_Async(points.ref, callback), (completer, p, p1) {
final radius = p1.cast<ffi.Float>().value;
calloc.free(p1);
completer.complete((Point2f.fromPointer(p.cast()), radius));
});
