feat: call tree in side panel that sync with source code

[lcottercertinia]

Is your feature request related to a problem?

It would be great to have a side panel that shows a call tree that syncs with source code. This would go to that line / method in vscode as each row in the tree is clicked. This needs to show cpu, heap, time

This would let devs easily find code perf issues with the context to hand.
