Rework and optimize block smoothing API
...
You now need to bring your own buffer instead of the smoother having a
built in vector you would need to pre-allocate. This makes the API
simpler, and also much more flexible when doing polyphonic modulation.
In addition, the new API is much more efficient when there is no
smoothing going on anymore.

Break PolyModulation into that and MonoAutomation
...
This is needed to properly support polyphonic modulation, since the
modulated value may still be automated in the meantime and the
polyphonic modulation must act as an offset for that value. This does
mean that the plugin must add the normalized value and normaliezd offset
by itself. The `PolyModulation` event now also contains a description of
how this can be used. It would have been nicer to be able to send
polyphonic automation-style events instead (like the PolyModulation was
doing before), but that's sadly not feasible without NIH-plug being
involved in the voice management.

Instead of 99.97%. Both numbers are not based on anything, but this

Rename ExponentialIIR -> Exponential
...
The suffix was added to denote that this could do some funny things
because of the snapping to the target value, but in practice that
snapping distance will likely be so tiny that it is likely not
noticeable.

Based on a one-pole IIR low pass filter that reaches 99.97% of the

will be less efficient than the linear FIR smoothing style.
