Add more technical indicators

[patriques82]

Currently not all indicators are implemented (far from all). This issue contains the majority of the work remaining. It is quite easy to implement a technical indicator since one can just follow the example of EMA, SMA, etc..

Since I want to finish this project as soon as possible it would be great if collaborators want help out with this. It is a good way to understand the design of the library and maybe make improvements after that.

The following marked indicators are implemented

• [x] SMA
• [x] EMA
• [x] WMA
• [x] DEMA
• [x] TEMA
• [x] TRIMA
• [x] KAMA
• [x] MAMA
• [x] T3
• [x] MACD
• [x] MACDEXT
• [x] STOCH
• [x] STOCHF
• [x] RSI
