Unable to decode a nested array of buffers

[mcuppi]

Attempting to decode an array of buffers in a larger buffer seems to fail.

Here is an example:

import { defineFormat, Type } from "tinybuf";

const Entity = defineFormat(6, {
  id: Type.String,
});

const GameState = defineFormat(7, {
  entities: [Type.Buffer],
});

// Encode
const buffer = GameState.encode({
  entities: [
    Entity.encode({
      id: "e1",
    }),
    Entity.encode({
      id: "e2",
    }),
    Entity.encode({
      id: "e3",
    }),
  ],
});

// Decode
const payload = GameState.decode(buffer);
payload.entities.forEach((entityBuffer, index) => {
  payload.entities[index] = Entity.decode(entityBuffer);
});
console.log(payload);

It seems like you can fix this by doing the following:

const payload = GameState.decode(buffer);
payload.entities.forEach((entityBuffer, index) => {
  const test = entityBuffer.buffer.slice(
    entityBuffer.byteOffset,
    entityBuffer.byteLength + entityBuffer.byteOffset,
  );
  payload.entities[index] = Entity.decode(test);
});

Not sure if there is a better / more appropriate way of extracting these nested buffers.
