Max Redpoint / Onsight / Flash indicators

Nkane 1 suggested (via Mountain Project):

Cool! I'd love to see Max Redpoint (including onsite, flash, redpoint) for trad and sport. That might show progression better (or at least differently) than the mean or mode. Or maybe top 5%.

I had this type of function planned out, so it is nice to see that people are interested in it as well. Shouldn't be too hard to add.

It could be a different color of overlaid dots on the Grades for Style graphs, one per year for redpoint, onsight, and flash.
