digital: Gut packet_utils.py
This module is a deprecated module and is used nowhere in GNU Radio, with the exception of a single variable (default_access_code). We keep that variable and remove all the rest. Because this module was the only consumer of crc.py, that was also removed. Signed-off-by: Martin Braun <martin.braun@ettus.com>
