Request for more succinct L2-per-channel mode

[skyreflectedinmirrors]

It's current a bit of a pain to analyze this. It would be far better (IMO) to have the default channel info be something like:

• min
• max
• mean / median
• std. dev

of each metric, over all 32 channels. The primary goal of these is to spot imbalances, and that's easier if you get aggregated stats, rather than a list of every value for all M metrics and N channels. Of course, having the current view as a "--detailed" mode or the like would be nice as well

Alternatively, we might design like this: (1) single metric for speed of light: use std.dev on top of avg per channel to indict "how imbalance" overall(any other better choice?). (2) box plot per channel shows min/max/mean/median clearly.

I think std. dev. (as a percent of the average) would be a good choice in the SOL

Added an "Aggregate Stats" table to the top of L2 Cache (per-channel) section. The table contains mean, std dev, min, max.

Feature complete. Feel free to try things out in our dev branch ahead of the next release.
