def get_data(start, size):
    '''
    read the given amount of data from the given start address.
    better than `idc.GetManyBytes` as it fills in missing bytes with NULLs.

    Args:
      start (int): start address.
      size (int): number of bytes to read.

    Returns:
      bytes: `size` bytes, filled with NULL when byte not available from database.

    # best case, works pretty often.

    # but may fail, when there's no byte defined.
