There does not seem to be support for range strings, but it could be
added. See value_string_from_table in epan/wslua/wslua_proto_field.c for
an example.

I suppose that the natural syntax would be:

    local your_range_string = {
        { 0, 24, "First quarter" },
        { 25, 54, "Second quarter" },
    };
