[BUG] Please implement the "threads" setting in Avisynth for NNEDI3Resize

[Selur]

when selecting NNEDI3Resize in Avisnth, the "ResampleMT" check box is greyed out,

That is correct, since there is ne ResampleMT-Version of NNEDI3Resize.

and the "threads" setting defaults to 1

That was added due to stability reasons when using MT.
-> Will remove the threads=1 unless Avisynth without MT is used. Don't plan to add the 'threads' option.
