But the section of file is enabled only for method 6, while should be enabled also for method 5.

i adjusted

• DeepExRefMerge to be 'no' for all external model methods aside from 2,5,6
  
• ScFrameDir to be 'None' for all file input is needed for 5,6
  

Updated Hybrid_deoldify.

DeepExRefMerge to be set 'no' for all external model methods not having RF same as video, which are: 2, 4, 6 <--- TO BE FIXED

The change of the names is to clarify better the source of Exemplar Models, which are models that are able to colorize a movie only if is provided a colored regerence image.
Previously were available 2 type of colored images: internal (provided by the picture color models implemented in HAVC) and external (external image files).
With HAVC 5.0 has been extended the external source of colored images to video clip. This extension was mainly added for restoring colored videos, but I preferred remove the HAVC prefix, because the clip could be generated by a different coloring model.

Thanks,
Dan
