Decode Utf16 produced by the above toString16() method.
If the output is provided off the stack, it should be large
enough to encompass the entire transcoding; failing to do
so will cause the output to be moved onto the heap instead.
Returns a slice of the output buffer, corresponding to the
converted characters. For optimum performance, the returned
buffer should be specified as 'output' on subsequent calls.
Where 'ate' is provided, it will be set to the number of
elements consumed from the input, and the output buffer
will not be resized (or allocated). This represents a
streaming mode, where slices of the input are processed
in sequence rather than all at one time (should use 'ate'
as an index for slicing into unconsumed input).
