webassembly module

[ksmoore17]

It would be good to have a webassembly module be part of this repository. In relation, the GitHub pages could have (alongside docs that are currently there) a simple interface for inserting a file, passing instructions, and cooking in browser (using this wasm).

To start, it could be as simple as taking a command line string like would be provided to a chef order like "sort; quantize -n 16;" and using the read_recipe method on CustomOrder to parse into a DishDescription.

All of the webassembly module would be in rust calling into python using pyo3; similar flow to the cli that will be implemented in rust (#9 first bullet).

I'm curious to see if web assembly in browser can handle cooking at least as well (memory/speed) as the 0.2.0 cli or if it will have to be done 50 frames at a time, for example, or if it's just totally chalked.

A next step would be to have a cli command that launches this wasm locally with a simple editor. Anything much further than that is beyond the scope of this repository (see https://github.com/pierogis/pierogis-live).
