Errors in README.md documentation for Breeze C# WebSocket usage sample code

[vivegi]

Issue:

The README.md has errors in the WebSocket Usage sample code.

Details:

Bug 1

• The API signature is incorrect in the WebSocket Usage example in the following line:

              // Subscribe stocks feeds
              Console.WriteLine(JsonSerializer.Serialize(await breeze.subscribeFeedsAsync((exchangeCode: "NFO", stockCode: "ICIBAN", productType: "options", expiryDate: "25-Aug-2022", strikePrice: "650", right: "Put", getExchangeQuotes: true, getMarketDepth: false))));
  

• The argument to subscribeFeedsAsync is not a record type object. There correct API signature is:

              public async Task> subscribeFeedsAsync(string exchangeCode, string stockCode, string productType, string expiryDate, string strikePrice, string right, bool getExchangeQuotes, bool getMarketDepth)
  

• The arguments must be passed individually
• As a result, the sample code doesn't even compile

Bug 2

• There is a non-existent API call used in the WebSocket Usage example in the following line:

              // UnSubscribe order notification feeds
              Console.WriteLine(JsonSerializer.Serialize(await breeze.unsubscribeFeedsAsync(true)));
  

• The correct API signature is:

              public Dictionary unsubscribeFeeds(bool getOrderNotification = true)
  

• There seems to be no async version of the above synchronous API call
• As a result, the sample code doesn't even compile
