`GetFutureHistory` and `GetOptionHistory` don't work for C# QuantBook

[DerekMelchin]

Expected Behavior

GetFutureHistory and GetOptionHistory work for C# QuantBook

Actual Behavior

If we run

var qb = new QuantBook();
var gold = qb.AddFuture(Futures.Metals.Gold);
gold.SetFilter(0, 90);
var history = qb.GetFutureHistory(gold.Symbol, new DateTime(2020, 6, 1), new DateTime(2020, 6, 5));
foreach (var slice in history)
{
    
}

we get

error CS1579: foreach statement cannot operate on variables of type 'FutureHistory' because 'FutureHistory' does not contain a public instance or extension definition for 'GetEnumerator'
