Incorporate Head & Shoulders into candlestick patterns

[superichmann]

As outlined in this QuantConnect blog post, QuantConnect team is developing innovative technical analysis patterns.

It would be nice to see the implementation of those advances in the CandlestickPatterns class and to be able to use them directly from LEAN.

According to github, no new CandlestickPatterns were added in the past 8 years.
