IsConsumed bool field for MultiQuery

I needed a way to add an unknown amount of query results to a List()
```
List<IEnumerable<dynamic>> resultSets = new List<IEnumerable<dynamic>>();

using (var sqlConnection = Utilities.GetCustConnection(requestData.ClientID))
using (var results = sqlConnection.QueryMultiple(sqlStatement, new { programID = requestData.ProgramID, itemID = itemID, profileTableOI = requestData.UserOI }))
{
    while (!results.IsConsumed)
    {
        resultSets.Add(results.Read());
    }
}
```
