This will allow passing both cli options and format options to sub decoder. Ex: pass keylog option to a tls decoder when decoding a pcap. Ex: pass decode options to a format inside a http body inside a pcap. Add ArgAs method to lookup argument based on type. This also makes the format decode function have same signature as sub decoders in the decode API. This change decode.Format a bit: DecodeFn is now just func(d *D) any DecodeInArg renamed to DefaultInArg
