Hey there!

I regularly profile addon CPU usage (for no particular reason) using https://www.curseforge.com/wow/addons/addon-usage.

I've noticed aux uses around 4-8 ms/s (milliseconds in a second) of CPU cycles while running in the background, no AH open, quite a bit after a fresh UI load.

Here's a screenshot of Addon Usage:

Quickly glancing at the code, I've noticed this is likely due to 2 unthrottled OnUpdate hooks in https://github.com/shirsig/aux-addon/blob/master/control.lua#L8 and https://github.com/shirsig/aux-addon/blob/master/control.lua#L55.
Doing a quick hack to throttle them to run at most once every 0.1s helped a lot and got it to consistently below 1 ms/s.

Now I imagine throttling like above would probably impact the performance of various addon operations (I've noticed these hooks coordinate listeners and coroutines).

What are your thoughts about this?
I'd be willing to get a PR up for throttling (perhaps configurable), if you think that's the right approach, and think this is an issue worth fixing.
