There's some backwards compat stuff that can reasonably be
removed, as well as a few new tricks I've learned (like using the Uint8Array version of reduce to convert strings).

Here are some of the updated functions:

function base64ToBuffer(b64) {
  let binstr = atob(b64);
  let arr = binstr.split("").map(function (ch) {
    return ch.charCodeAt();
  });
  return Uint8Array.from(arr);
}

function bufferToBase64(buf) {
  var binstr = buf
    .reduce(function (arr, ch) {
      arr.push(String.fromCharCode(ch));
      return arr;
    }, [])
    .join("");
  return btoa(binstr);
}
