Feature request: debug value flow like in Max

[eleses]

Right now Audion doesn't display any parameter values, nor any actual data flow.

At least for constant values of parameters, i.e. not modulated, it would perhaps not be too hard to display in the details pane on the left when a node is selected (on the right). But a "signal probe" like Max does, in its debug mode, would be even more useful in Audion, although arguably that's more work.

Also, the "render capacity" % reported by Audion is very optimistic. In reality, one-core usage is about 10 times higher than reported in Audion, on a Zen 3 cpu at least.
