Add serial monitor send/receive encoding options
- Add "send as <encoding>" dropdown menu. - Add "receive as <encoding>" dropdown menu. Sending and receiving can be done in any encoding specified in StandardCharsets with the additional option to send comma-separated bytes and receive newline-separated bytes directly. This fixes #4452 and offers an easy implementation for issue #4632.
