[Suggestion] support TimerOutputs

[rapus95]

As I recently started using Makie and fell in love with its clean design (at least from my perspective :D) I did a jump start, making 6 plots in parallel (with MakieLayout) and fast began to struggle, because it kind of lags when moving those linked plots (aka all 6 areas move when I drag one). Thus, it might turn out to be quite helpful if there were some clever TimerOutput macros placed at the most relevant points. It might even help if people report latency/lag bugs.
