Pixel counter

Quick edit: Changed v2 files because yesterdays version included the old version in the same sbs
-----------------------------------------

A node for Designer which counts the number of pixels of a given color within a certain margin of error.
Target color is rounded towards the nearest true value in whatever bitdepth is used.

------------------------------------------

Version 1:
- Quite performance heavy
- max working resolution of 4096x4096
- possibly still interesting for learning purposes

Version 2: ---(Awaiting approval)---
I realized there is a much more efficient way of doing this. Which also
happens to be a lot simpler.
- Different method
- Fast performance
- No max resolution

Contains .sbs files for both versions.
Requires SD 11.1.1 or newer
