Some DSCP values can be translated to symbolic names. That may not be
always desirable. Introduce a command-line option similar to other tools,
-N or --Numeric, to suppress this translation.

Notes:
    v2:
    - Make it -N / --Numeric instead of -n / --no-nice-names
    - Rename the flag from no_nice_names to numeric as well
