True. This *will* a separate API, and using it directly will
by far the easiest way, but

1. Given that basic LV2 is almost nothing, *any* extension
more or less corresponds to a complete redeifinition (with
only the run() call being standard). So it's not really
so special.

2. 'Embedding' it in LV2 may placate some people, and
save me some flames.

More generally, I don't think you can do automation right
by just monitoring/injecting control port values. Except
maybe when the automation data has a constant rate, e.g.
1/16 FS. In all other cases, it's only the plugin that can
decide in any intelligent way on control points, their
frequency and/or step size, etc. and it's only the plugin
that can interpolate such data in the correct way.

At least the compressor has other issues as well (didn't test the
others).
