+When given, decoder "raw" data of various kinds is written to stdout instead
+of annotations (this could be raw binary UART/SPI bytes, or WAV files, PCAP
+files, PNG files, or anything else; this is entirely dependent on the
+decoder and what kinds of binary output make sense for that decoder).

+No other information is printed to stdout, so this is

+Protocol decoders that support binary output publish a list of binary
