Slight mask optimization #1

For L134 it's a little faster to use the built-in parameter scale=2. The results are not exact but are ±1 with integer formats so that can be chalked up to rounding errors.

A quick test with ffms2 video input gave me

264fps vs 285fps in 8 bit
211fps vs 241fps in 16 bit
150fps vs 191fps in 32 bit

You can put external whateveryouwant mask clip and it will have zero overhead against internal one. The bottleneck of this script is not a mask anyway, but eedi3.

Yeah that's more or less why I didn't bother to make it a PR, but it wouldn't hurt to add it in next time there's a meaningful update.

I'll probably break things once again and allow to pass kwargs into filters in the next updates.
