feat: dim zero bytes

[tomilho]

Greys out zero bytes to make non-zero data stand out. Credits to @armandas for the CSS. Closes #419

I think this change looks good, but I wonder if we should be thinking in the long term about how this works with generic colorization (as popularly requested in #50 among others.)

(#50 and/or finishing the GPU renderer is on my mind as good candidates for hacking over the upcoming holiday season)

[tomilho]

I like your way of thinking! 😊 Both projects sound really cool to me, so I'd be more than happy to help in any way I can. Let me know what I can do!

I looked over the binary template as I have never used them before and I think we would be doing something similar to diffing:

1. Parse binary template
2. Create hex decorators (like the insertion/deletion decorators; maybe with more information e.g name, type?)
3. Render them in the hex editor.

So, I think most the work would be figuring out the binary template process would look like...

Regarding GPU rendering, I tried the canvas changes and they are incredible (barely saw any hiccups when scrolling over a large file), so I think this should be a priority over the binary template

If you agree, I can start working on the GPU rendering. Or we can take a different approach - I'm up for anything :)

The canvas branch works okay, but is still technically a CPU renderer and rendering of text is only marginally better than DOM (at least last time I tested it.) I want to explore doing an approach using WebGPU, and move things a little further away from React so that rendering is better optimized. These are some pretty big changes and I still need to re-ramp on webgpu stuff, it's been a while since I touched shaders (most recently was the js-debug flame chart, though that is webgl and not the newer webgpu)

I'll need to learn shaders to be able to help you, but (hopefully) I don't see that being an issue. Let me know when you are ready to dive into this, in the meantime I will get up to speed on shaders stuff and explore different binary templates!
