[PW]D/W/M/Y pivots with S/R levels

I could not find a pivots script that was entirely to my liking on TV so I re-worked this from the '[RS]Shifted Pivots V1' script by RicardoSantos.

You can choose which timeframe pivots you would like to display from day, week, month, and year.

You can also choose how many levels of S/R you would like to show.
