Triple barrier labeling visualization

[hamidm21]

Here are the essentials that should be visualized:

1. Barriers (upper, lower, and vertical barriers)
2. Touched point (this is the exact point where one of the barriers is touched)
3. Backward window or range (this is the number of candles that have been used to calculate the barriers)

Here are the extra visuals that could help the plot:

1. The multiplier of the barriers (upper and lower barriers are multiplied by a factor which could be shown)
2. volatility in the backward window (this is not shown nicely with a line, maybe it could be shown as a box?)
3. The relation between the backward volatility and the barriers (I'm not sure how we could show this)

I highly recommend checking out this documentation and their examples to get new ideas.

Keep in mind that the plotting function should return one window at a time and it should be parameterized to take the number of the window as an input.

Also, make sure to add a new notebook and call it visualizing triple barrier. This way you and Amirreza can work separately.
