proto: can't skip unknown wire type 7

[martea]

trying to use hercules combine in windows, to combine hercules results from the --burndown but ending up with same error.

@martea : It could be helpful if you provide a reproducible case that others could also execute.

This occurs because of using hercules -m burndown-proxy ... > file.pb without --pb flag on previous steps.

Without --pb flag, hercules generates text representation, that cannot be parsed by hercules combine file1 file2 ... -- combile will fail with such parse error.
