Examples for using QueryStringBuilder

[ManfredLange]

While generally it shouldn't be too hard to use the QueryStringBuilder, it'd be great if either in the tests or in the wiki (or both?) there would be some examples for how to use the QueryStringBuilder, e.g. for the qsb parameter in IStockPricesService.HistoricalPriceAsync().

Perhaps such examples already exist. Then perhaps adding a link in the README.md or in the wiki (or both?) would be helpful.

Thank you and keep up the good work!

If you check the implementation of IStockPricesService you can see some usages of it.

IEXSharp/IEXSharp/Service/Cloud/CoreData/StockPrices/StockPricesService.cs

Lines 55 to 57 in c867f10

	qsb = qsb ?? new QueryStringBuilder();
	if (chartByDay)
	qsb.Add("chartByDay", "true");

That provides a starting point. Thank you!
