If the midi message is a sustain or sostenuto, pass it on regardless of the plugin-side automation compile time switch.
Also hide sustain/sostenuto CCs from the UI controls; most of the time they're for pedal noises and things like this.
Previously, some `patch:Set` messages were directed to a distinct atom
port, when it was for notification purposes rather than automation.
Ardour does not support this, and the ports get assigned the same
buffer, producing corruption.
This commit returns to single-port behavior, and instead replaces
`patch:Set` notification messages with `sfizz:Notify` custom objects;
the UI processes these messages all the same, and they does not trigger
automation in the host.
