Added throttling reasons and cpu uptime (#507)

* Added throttling reasons and cpu uptime

* spotless

* adding tooltips for the acronyms used

* Added icon for suggesting folks should attempt a hover-over for tooltip

* wip making the implementaiton more platform independent

* spotless

* wpiformat

* wpilibformat pt 2
