[FEATURE REQUEST] Add standard deviation to Node Analytics

[brayevalerien]

This extension is very usefull for benchmarking models at different precisions quickly, I use it quite a lot.

What is missing though for this kind of comparisons is a way to get the standard deviation is execution time and VRAM usage in addition to the average.

This could be added in the Node Analytics tab and in the Latest Workflow Run stats too.

Hell yea I am glad you're using it!

Is there anything else that we could add? I will make a list

[brayevalerien]

Thanks a lot for taking the time to take notes of recommendations!
For the moment, only the real time usage plots I mentioned in #2 and the display of the standard deviations in the different panels come to my mind, but I will let you know if anything else is missing for me.

Coming back to you after so more testing, I thought about another nice feature that would help debugging and profiling workflows.

I might need to open a new issue for that though, tell me.

Allowing the user to record a snapshot of the memory usage using the torch feature described here.

This is especially usefull for knowing what model made the workflow crash or what are the bottlenecks of a workflow and when they occur.
