Look at the contents of a data frame: copy data as raw (to paste buffer)

```
pbpaste | cut -c 11- | xxd -r -p | protoc --raw_decode
```

Drop the first 10 characters (first 5 bytes: the gRPC frame header), encode as binary, decode as raw protobuf.

You won't see field names, but you will get field numbers.
Try to match the field numbers and types to known protobuf message types using your brain.
