Data requested is too large. `resolution=auto`

When trying to request chartdata that starts 13 years ago (even tho there is not that much data).

    raise PoloniexError(out['error'])
poloniex.PoloniexError: Data requested is too large. Please specify a longer period or a shorter date range, or use resolution=auto to automatically calculate the shortest supported period for your date range.

Might be worth looking into adding resolution=auto to returnChartData

seems around 3-4 months is the max for 5 min candles
