Faster-than-native toHex() for JavaScript Uint8Arrays

  Firefox 133b7 and Safari Tech Preview both have a new Uint8Array.toHex() method, but otherwise browsers don't yet have a native way to turn binary data into hex strings.

  I put this tiny package together to fill this gap using a significantly faster technique than I've seen elsewhere.

  Surprisingly, it's actually faster than the current native Firefox implementation (at least on a recent MacBook Pro). Hopefully that won't remain the case for too much longer ...
