Should RGB images set the legacy "RGB color" flag?

When opening an RGB image such as a 24-bit PNG via the File > Open method, ImageJ2 does not report the data type as "RGB Color". In IJ2, there is no difference between this and 3-channel unsigned 8-bit integer, but for IJ1 legacy plugins it matters.

Should we set the RGB flag in such cases?

Hopefully it will be sufficient to support saving 3-channel unsigned 8-bit integer datasets as RGB (maybe as an option). As for legacy plugins, the File > Open command using SCIFIO will probably always open as a composite image; users can manually change it back to RGB Color mode if they need that. This might break old macros though, so we should consider things carefully.
