Deoldify Vapoursynth filter

[Dan64]

I released a new version: https://github.com/dan64/vs-deoldify/rel...tag/v1.1.0

New parameters has been added to control the combination of 2 models.
The parameters added are:

1. dd_weight: weight assigned to ddcolor, if = 0 ddcolor will be disabled (default = 0) [range: 0-1]
   
2. dd_strength: ddcolor input size, if = 0 ddcolor will be disabled (default = 1) [range: 0-4]
   
3. dd_model: ddcolor model: 0 = ddcolor_modelscope, 1 = ddcolor_artistic (default = 0)
   
4. dd_num_streams: number of CUDA streams to enqueue the kernels (default = 1)
   

The strategy adopted to combine the 2 models is a simple Merge.
I will evaluate the possibility to improve the combination of the 2 models (it would be an option to de-saturate one of the 2 models)

I hope that you can integrate the new parameters in Hybrid.

Thanks,
Dan
