hioOiio: update usage of deprecated version of ImageInput::read_image()

As of OpenImageIO v3.0.0.3, a set of deprecated overloads of
ImageInput::read_image() were removed. This change unrolls
the overload that was being used into its equivalent in the
current API, which was also available in OpenImageIO 2.x.
