> Implement the following UDFs:
> <array> map_keys(<map>)
> and
> <array> map_values(<map>)
> map_keys() takes a map as input and returns an array consisting of the key
> values in the supplied map.
> Similarly, map_values() takes a map as input and returns an array containing
> the map value fields.
