This is the first step in transitioning Piano to a full LibDSP backend. For now, the delay effect is replaced with a (mostly identical) implementation in LibDSP. The new ProcessorParameterSlider attaches to a LibDSP::Processor's range parameter (LibDSP::ProcessorRangeParameter) and changes it automatically. It also has the ability to update an external GUI::Label. This is used for the three delay parameters and it will become useful for auto-generating UI for Processors.
