/*
Summary:
WavetableGroup manages a collection of WavetableComponents, each potentially generating or modifying waveforms. It allows adding, removing, and reordering components, provides methods to render their combined output at any position in the wavetable, and handles serialization. By grouping components, it supports layering and complex combinations that form part of a larger WavetableCreator pipeline.
