Deoldify Vapoursynth filter

I attached the new (updated) RC7, main changes are:

   1) decreased the client connection timeout from 600sec to 60sec.
   2) removed the parameter encode_mode from HAVC_cmnet2dit(), only remote processing is supported due to the memory limitation of local approach

I suspect that there is something that is blocking the client/server connection on your side, with the new timeout it will be necessary to wait only 1min. before see a connection error, previously it was necessary to wait 10min.
