/** Deliberately VST2-specific (unlike everything else in this tool): talks
	to the raw AEffect dispatcher directly, bypassing JUCE's own
	VSTPluginInstance::usesChunks() gate.

	Why this exists: JUCE's generic AudioProcessor::getStateInformation()/
	setStateInformation() only reach a VST2 plugin's real effGetChunk/
	effSetChunk implementation if the plugin's AEffect.flags advertises
	effFlagsProgramChunks. JaySynth's compiled JUCE 3.1.1 VST wrapper never
	sets that flag (see tools/testhost/TODO.md's Investigate section), so
	the generic path silently falls back to JUCE's own per-parameter
	"regular" fxb/fxp format instead - which never touches JaySynth's own
	bankEncodeXml/bankDecodeXml or patchEncodeXml/patchDecodeXml at all.

	Many real-world VST2 hosts don't strictly gate on that flag either -
	they just call effGetChunk/effSetChunk and see what comes back. This
	does the same thing on purpose, to reach and test that actual code
	path.
