Subroutine gdf_read_uvonly_codes allows to read only the columns containing the requested codes. On input, UVT and TUV order are supported.

For example, if the requested codes contains

$$code\_uvt\_u,code\_uvt\_v$$

, it would return the U and V values for all visibilities (in this example, gdf_read_uvonly would return the same information, but in a transposed way).
