/**
 * 4cc = "{@value #TYPE}"
 * siDecompressionParam Atom ('wave')
 * The siDecompressionParam atom provides the ability to store data specific to a given audio decompressor in the
 * SoundDescription record. As example, some audio decompression algorithms, such as Microsoft’s ADPCM, require a
 * set of out-of-band values to configure the decompressor. These are stored in an atom of this type.
 * This atom contains other atoms with audio decompressor settings and is a required extension to the sound sample
 * description for MPEG-4 audio. A 'wave' chunk for 'mp4a' typically contains (in order) at least a 'frma' atom, an
 * 'mp4a' atom, an 'esds' atom, and a “Terminator Atom (0x00000000)” atom.
 * The contents of other siDecompressionParam atoms are dependent on the audio decompressor.
 * 

 * Size - An unsigned 32-bit integer holding the size of the decompression parameters atom
 * Type - An unsigned 32-bit field containing the four-character code 'wave'
 * TrackExtension atoms - Atoms containing the necessary out-of-band decompression parameters for the sound decompressor.
 * For MPEG-4 audio ('mp4a'), this includes elementary stream descriptor ('esds'), format ('frma'), and terminator atoms.
 * 
 * Possible paths: /moov/trak/mdia/minf/stbl/stsd/mp4a/wave/esds or /moov/trak/mdia/minf/stbl/stsd/mp4a/wave/mp4a/esds
