JVET-AI0107 SADL models, model and quantization scripts
The MR includes sadl models, model and quantization scripts, and json files.
The architecture is the same as LOP3, but the model script is slightly different from LOP3, since it uses different values in C_Y and C_UV to adjust complexity, while LOP3 uses the same value C for C_Y and C_UV. The same change applies also to C21_Y and C21_UV. Therefore the LOP3 script is not reused.
