Socket routing improvements, unit test cleanup (#276)
Updated WebSocket message routing improving performance for scenarios with multiple different subscriptions and topics Added AddCommaSeparated helper for Enum value arrays to ParameterCollection Improved EnumConverter performance and removed string allocation for happy path Fixed CreateParamString extension method for ArrayParametersSerialization.Json Fixed Shared GetOrderBookOptions and GetRecentTradeOptions base validations not being called
