`config`	`NumberCodecConfig`	Optional configuration to specify endianness (little by default).

FixedSizeDecoder<bigint, 8>

A FixedSizeDecoder<bigint, 8> for decoding u64 values.

Decoding a u64 value.

const decoder = getU64Decoder();
const value = decoder.decode(new Uint8Array([0x2a, 0x00, 0x00, 0x00, 0x00, 0x00, 0x00, 0x00])); // 42n
