wgrib2: -vector_dir

Bit 5 of the flag 3.3 indicates whether vector quantities are relative to the
grid or the North/South poles.
The -vector_dir option writes out "winds(N/S)" or "winds(grids)"
depending on the value of the flag. Note there is no flag that indicates whether
the quantity is a U/V component of a vector.
