IQFeed client causes app crash

[samushenkov]

#122 issue can cause app crash if one uses GetIntervalMessagesWithRequestId api method.

SocketAsyncEventArgs.Completed event handler doesn't have any try-catch blocks. That is why exception thrown by ParseWithRequestId crashes all application.

@samushenkov just by curiosity, why are you still using requestId?

[samushenkov]

Actually I am not, it was a first attempt to solve an issue with candles received from previous request. Just thought that there is some logic that filters messages based on request id.

@samushenkov we still dont use TryParse for RequestId thats the reason why you got the exception. https://github.com/mathpaquette/IQFeed.CSharpApiClient/blob/master/src/IQFeed.CSharpApiClient/Lookup/Historical/HistoricalMessageHandler.cs#L27
