Struct AdpcmState 

pub struct AdpcmState {
    pub channel_layout: Channels,
    pub frame_length: usize,
    pub channels: Vec<AdpcmChannelState>,
    pub frame_bytes: usize,
    pub header_bytes: usize,
    pub header_size: usize,
    pub encoding_type: SampleType,
    pub sample_rate: u32,
    pub current_header: Option<Vec<u8>>,
    pub low_nibble: bool,
    pub pending_byte: u8,
    pub current_channel: usize,
}

Manages the state for ADPCM and PCM encoding/decoding within a stream.

This state handles the framing, headers, and adaptive predictor values for ADPCM. Although it is named AdpcmState, it supports all formats defined in SampleType, including 8-bit and 16-bit PCM.
