Add st param to functions using nnedi3cl

In some systems, NNEDI3CL can raise cpu usage to 100% when running in multi-threaded mode. Having the option to force NNEDI3CL to run in single-threaded mode can be quite beneficial.

Is there a way it can be reproduced? Minimal example.

Apparently Asd-g was not able to reproduce it, so I'm not sure. It might just depend on your setup. I know that for me with this script, changing st to true will substancially reduce cpu usage while keeping a very similar performance

I did a pull request for this, had similar issues with NNEDI3CL (thou also crashes), and st=true seems to fix it.

[Dogway]

Ok, will merge if Asd-g doesn't solve issue 6 by end of week. Self-reminder to also update SMDegrain, SharpenersPack, ChromaReconstructorMod, and TransformsPack - Main.

[Dogway]

Check if commit fixed it

Open back if you get any issues.
