MFI Reloaded @ByPuppyTherapy

The goal was to create a nicer cleaner and yet a practical version of the
MFI indicator. MFI or Money Flow Index is a momentum-based oscillator. It is very similar to the RSI but enhanced with
volume in its calculation.

This version of MFI features :

• - Cleaner visualization
  - EMA Band Ribbon to see the trend without noise
  - Long Term MFI smoothed via T3 that sets the actual trend
  - basic TDI like functionality with two bands and Sharkfins / Hooks
  - the Sharkfins / Hook signals are generated in the direction of the MFI Trend
