Inline Wasm into JavaScript source

[timfish]

Currently the wasm is in a separate file and is loaded like this:

const path = require('path').join(__dirname, 'orchestrion_js_bg.wasm');
const bytes = require('fs').readFileSync(path);

const wasmModule = new WebAssembly.Module(bytes);
const wasmInstance = new WebAssembly.Instance(wasmModule, imports);

This will not be compatible with some bundlers which may be an issue in some use cases.

We could run a post-build script that inlined the wasm as a base64 string like this:

const bytes = Buffer.from('2.6MB-data-in~3.5MB-base64-string==', 'base64');

const wasmModule = new WebAssembly.Module(bytes);
const wasmInstance = new WebAssembly.Instance(wasmModule, imports);

Potential Issues

• The uncompressed package will be 33% larger
• Might impact startup performance
