Deoldify Vapoursynth filter

[Selur]

for some reason is filled the parameter "sc_framedir" even if in the GUI the directory box is empty.

Hybrid does set the default temp folder if sc_framedir/ScFrameDir is empty.

I:

• removed the 0.01 minimum adjustment for sc_threshold
  
• only add sc_threshold, sc_min_freq when DeepEx is used (sc_threshold is now disabled unless DeepEx is enabled, and sc_min_freq is disabled unless DeepEx is used and DeepExMethod == 0
  
• ScFrameDir and sc_framedir will not be set if they are empty.
