/**
 * Implements CRC-64/NVME checksum algorithm.
 *
 * This class provides CRC-64 checksum calculation using the NVMe polynomial (0x9a6c9329ac4bc9b5).
 * It uses an 8-slice lookup table for efficient computation.
 *
 * @example
 * ```typescript
 * const checksum = new Crc64Nvme();
 * checksum.update(new Uint8Array([1, 2, 3]));
 * const result = await checksum.digest();
 * ```
