Superfast Mandelbrot generator v2

It is based on an algorithm published on pouet in 2021. It uses 4 colors and flashing (or quasi-interlacing) to simulate 8 colors. Generated pictures are 128x256 raster images. It is very likely that this algoritm implementation is the fastest known Mandelbrot set computation routine for the 6502.

The prg-file for the flashing variant is here and the prg-file for the quasi-interlaced variant is here.
