Note #
This realisation has some difference with the original lib. It's location clamping. Original geohex.org uses double representation of lat'n'lon, so theoretically, it should take more precision etc. but in fact, it leads to errors.
Refer to this - decimal degrees, eight points after dot the should be enough for everything.
