Option to remove dashes

Sometimes there is a requirement to get 32 character UUID (may be I shouldn’t call that UUID 😃 ). However the UUID generated by this library is 36 chars length. Because of dashes.

Is it possible to add an option to omit dashes? Something like this:

function v4(options, buf, offset) {
    ...
    return buf || bytesToUuid(rnds, 0, options.nodash);
}

function bytesToUuid(buf, offset, nodash) {
  var i = offset || 0;
  var bth = byteToHex;
  return  bth[buf[i++]] + bth[buf[i++]] +
          bth[buf[i++]] + bth[buf[i++]] + (nodash ? '' : '-') +
          ...
}

@LeoDupont: I have zero interest supporting non-standard id formats.

@broofa : I also need to get non-canonical UUIDs (without dashes), and it may be the case for many users.

Indeed, using replace() works, but it might be a nice touch to add an option that would not include the dashes in the first place, for better performance and cleaner code.

What are your thoughts?
