CQP & Poliqarp: Error for unknown flags #176
Description
Unknown flag such as the example below is just ignored in the serialization.
"Fraulein"%s
It would be more transparent and informative to throw an error g, e.g. Flag s is unknown.
A combination of known and unknown flags such as the example below:
"Fraulein"%cs
returns errors:
[302, "Failing to parse at symbol: '\"'", 13 ],
[ 302, "Could not parse query >>> \"Fraulein\"%cs <<<." ]
As the first example, an error should be thrown.
