make_point
function to make a point out of a Y (latitude) and X (longitude) coordinate.
Note that the Y component (latitude) comes first
Examples:
make_point(47.123124, -123.325232)
-- Result: {"type":"Point","coordinates":[-123.325232,47.123124]}
make_point(to_number(text_number_column), to_number(text_number_column))
-- Result: {"type":"Point","coordinates":[42,42]}
