[Feat]: furthest/closest to zero

[withinboredom]

Problem

Sorry if this has been asked for before, but this one was a bit hard to search for.

Currently, when looking at certain stats (like clock offset), I'm usually interested in looking at the "furthest from zero." Right now, I have to look at the max and min and figure out which one is further from zero.

Description

Add a new filter, along with average, min, max, sum.

Importance

really want

Value proposition

1. Not all stats unsigned, some go both negative and positive. In these cases we usually are asking the question: "how close/far are my nodes from zero?"

Proposed implementation
