Ichimoku (with Future Cloud)

This is an Ichimoku indicator with the cloud projected into the future (missing in another version found on here). It uses shifts to move the lagging span and cloud. I also handled the cloud fill differently, just with more line plots, for simplicity.

Working on getting it shared in the community indicators. It asked for this link.

P.S. Not sure how the sharing works with dependencies (it only depends on existing things) but if that is not done right let me know, will try to fix.
