Fixing the PNG data processing issue that occurs sometimes in Firefox. #3

Hello @saharan!

Life Universe has recently garnered interest on Hacker News. Well done and well deserved! I love this project and your techniques, and I'm happy to see my old language of choice Haxe play a role in someone's extraordinary project.

There seem to be anti-fingerprinting features in recent browsers that can cause the result of CanvasRenderingContext2D::drawImage to be inaccurate, which has made the project inoperable in some visitors' browsers. This PR contains a basic fix that uses the haxe.format library to decode the PNGs loaded with the fetch API, circumventing the whole fingerprinting problem.

My goal was to fix this quickly in the short term, but in the long term, you may wish to use a different file format than PNG to represent this data.

This contribution requires no attribution whatsoever. It's a pleasure to meet you!

Hello, Rezmason!

I'm very happy that there are so many people having fun with it!

Oh my, I didn't expect that. Is that because of a security concern? I wonder if there might be a better way...🤔 Anyway, thank you for the contribution! Now that JavaScript natively supports compressed streams, it may be a good time to say goodbye to image-based data compression.

Thank you, saharan
