    Interface AdvancedLzwDecodeOptions

    Advanced options, allowing for full control of the initial dictionary/decoding state.

    import { Lzw } from '@4bitlabs/codecs';

    const dictionary = [
    Lzw.EOF_MARKER,
    0x41, // A
    0x42, // B
    0x43, // C
    0x44, // D
    ];

    const bytes = Lzw.unpack(encodedBytes, { dictionary });

    Longer codings can be encoded in the dictionary by using either an array of numbers of with a Uint8Array:

    import { Lzw, EOF_MARKER } from '@4bitlabs/codecs';

    const dictionary = [
    Lzw.EOF_MARKER,
    Uint8Array.of(0x47, 0x41, 0x54, 0x41), // GATA
    Uint8Array.of(0x41, 0x54, 0x54, 0x41), // ATTA
    Uint8Array.of(0x43, 0x47, 0x41, 0x54), // CGAT
    Uint8Array.of(0x41, 0x43, 0x41, 0x47), // ACAG
    ];

    const bytes = Lzw.unpack(encodedBytes, { dictionary });
    interface AdvancedLzwDecodeOptions {
        dictionary: InitialDictionary;
        order?: "msb" | "lsb";
    }
