I’ve made a dither code that uses a buffer and getRows/setRows, and is ~105-107% faster (~205-207% of the speed) on my pygamer!

I’m most likely going to use this in my [screen effects extension](https://forum.makecode.com/t/screen-effects-extension-development-q-a-feature-requests/16246) (with a slightly changed sequence of dithering, and credit in a code comment for @hasanchik’s idea/coding and @kwx 's/your  
(@AqeeAqee’s) contributions to optimizing this code).
