Flame graph should display when the call tree is inverted

[gregtatum]

I've been profiling things lately where the inverted call tree is really helpful, especially as these highlight when heavy allocations are causing slowdowns.

I would like to toggle between the inverted call tree and the flame graph to see what is going on. This could be accomplished through a selector.

Pseudo-code:

export const getInvertCallstack: Selector<boolean> = (state) => {
  switch (tabSlug) {
    case "flame-graph":
      return false;
    default:
      return getProfileSpecificState(state).invertCallstack;
  }
}

I'm not sure if there are realistic plans to support the inverted view in the flame graph due to perf reasons, but this would get rid of the annoying switching button.
