v1.6.9

What's Changed

• Modified the GetHistoricalData method to return a single class of stock data values to make it easier to parse through the data by @ooples in #93
• Made sure volume value type was changed to long since it was throwing an exception for certain symbols by @ooples in #94
• Went ahead and changed all volume data types to int 64 since some exceptions were still happening by @ooples in #95
• Replaced some volume values with long instead of double by @ooples in #96
