• Fixed a bug in parsing quote API for indices
  
• Fixed a bug in receiving ticker packets that resulted in partial tick data while subscribing to many instruments at once.
  
• Added new trigger range API that supports bulk fetch

  TrigerRange triggerRange = kite.GetTriggerRange(
                  Exchange: Constants.EXCHANGE_NSE,
                  TradingSymbol: "INFY",
                  TrasactionType: Constants.TRANSACTION_TYPE_BUY
  );

  Changes to:

  Dictionary <string, TrigerRange> triggerRange = kite.GetTriggerRange(
                  InstrumentId: new string[] { "NSE:ASHOKLEY", "NSE:INFY" },
                  TrasactionType: Constants.TRANSACTION_TYPE_BUY
  );

• Changes in TriggerRange structure:

  Beta 1	Beta 2
  _	InstrumentToken
  Start	Lower
  End	Upper
