docs: r"""Use this to grab a "string" from a bytearray() stream.
  
      C's printf() prints until it encounters a null byte (b'\0'). This function behaves the same.
  
      Positional arguments:
      stream -- bytearray stream of data.
  
      Returns:
      bytes() instance of any characters from the start of the stream until before the first null byte.
