[RS]ZigZag Multiple Methods - Forecast - patterns - labels

experimental:
zigzag indicator with all the zigzag methods that im aware of(that matter atleast), theres something for all tastes there :P
this will be the basis for zigzag tools i make in the future.

note: some zigzags REPAINT.

Catatan Pelepasan: improved range based methods to detect reversals, still not perfect(sometimes it uses a previous bar it should not), but atleast it will act better with volatile markets when the range is smaller that the volatility level.

Catatan Pelepasan: Added a very requested leg volume information to labels (currently attached to price label) this may change later with addition of other volume metrics

Catatan Pelepasan: modified color profiling (work in progress)
changed likely square to use box function
overhauled line/label system using arrays for better control.

Catatan Pelepasan: v5 update, removed pattern detection individual options as its handled in a library now, added color option for reverse line, text size option, fixed minor bug with reversal line and improved labels pattern text position.

Catatan Pelepasan: zigzag function is now handled in external library.
