Currently we have a wasm wrapper that only works with wasm files specifically generated by wasm-pack with wasm-bindgen. It would be very cool to have a wrapper that works with more generic wasm modules.

For this we also need to implement a new memory management strategy which is outlined here:

One downside of the new approach is that we cant really cache anything with it. Currently we dont reexecute nodes when their inputs dont change:

Link to Code

let inputHash = `node-${node.id}-${fastHashArrayBuffer(encoded_inputs)}`;
let cachedValue = this.cache?.get(inputHash);
if (cachedValue !== undefined) {
  results[node.id] = cachedValue as Int32Array;
  continue;
}

results[node.id] = node_type.execute(encoded_inputs);

Hmm, actually this branch already works pretty well 😂 There are no memory leaks and the performance is comparable to main

`main`	`feat/remove-wasm-bindgen`
