read_into(read_buffer, count, offset)
      Read up to `count`, `engine_link.available()` or `len(buffer)`, whichever is smallest into `buffer` starting at `0` or from `offset` if passed. If data is not read fast enough and `engine_link.available()` reaches 511 and new data is received, the oldest data is overwritten.
Parameters:
      read_buffer [value: bytearray, type: bytearray]
      count [value: int (optional), type: int]
      offset [value: int (optional), type: int]
Return Value: Number of bytes read into `buffer` (int)
