+`BrowserBuffer` is the browser `buffer` module (this repo). `Uint8Array` is included as a
+sanity check (since `BrowserBuffer` uses `Uint8Array` under the hood, `Uint8Array` will
+always be at least a bit faster). Finally, `NodeBuffer` is the node.js buffer module,
+which is included to compare against.
