Natural Log Fractal

Created by iterating z' = ln(-z) / ln(z). I haven't seen this fractal anywhere else, discovered it while messing around with some shader code. Reproduced here to learn multithreading in Rust.

Usage:

git clone https://git.signorovitch.org/jacob/ln-fractal && cd ln-fractal
make

This will generate a series of frames zooming into the fractal (default is 20), and link them together into a video. May take a while to run, depending on your CPU. The video is saved as output.mp4, and the frames can be viewed directly in imgs/.
