// Button handling for RC5 and RC6 Remotes
// - these send a toggle bit on every new button press, so it is easy to differ hold and re-pressing
// - on re-pressing this function will send the button again immediately. it uses the _currPrefix which has to be passed by the calling function
//   and which must be only the single byte of the RCx code containing the toggle bit
// - if a button is held down, the remote will not toggle this bit and goes on sending the same code every 100ms or so
//   this function will then, after some ignored codes, start with some slow repeats, then switch to medium repeat rate and finally repeat with the rate of the incoming codes
