Support Worst-Case Stack in symbol listings

[george-palmsens]

Hi! Fantastic tool, thank you so much for your work.

I frequently use Puncover to find the worst case stack usage of a function. It would be exceptionally useful if I could see this information as a column in the symbol list, just like I can see the per-function stack usage.

This would let me easily identify functions in my binary that lead to a ton of stack pressure.
