Tweak/optimize VST callback:
The audioMasterAutomate callback from plugin to host does include
the parameter-value.
Previously there was a redundant call
Plugin::parameter_changed_externally() -> get_parameter
-> VSTPlugin::get_parameter() back into the plugin to query the value.
calling back into the plugin from the callback, may explain
oddities and/or crashes with some VSTs.
