- v6OrderedToV1() Not implemented

## Usage

```ts
import * as uuid from "uuidv6-extension";

// nil
console.log(`nil UUID: ${nil()}`);

// Parse - Stringify
const uuidV1 = uuid.v1();
const uuidV1Parse = uuid.parse(uuidV1);
const uuidV1Str = uuid.stringify(uuidV1Parse);
const uuidV6 = uuid.v6();
const uuidV6Ordered = uuid.v6Ordered();

console.log(`UUID v1: ${uuidV1}`);
console.log(`UUID v1 stringified: ${uuidV1Str}`);

// Validate
const invalid = "ad333a";
console.log(uuid.validate(uuidV1));
console.log(uuid.validate(invalid));
console.log(uuid.validateV6(uuidV6));

// Version
console.log(uuid.version(uuidV1));
console.log(uuid.versionV6(uuidV1));
console.log(uuid.versionV6(uuidV6));

// UUID to Date
console.log(uuid.uuidToDate(uuidV1));

// UUID V6 with ordered timestamp
console.log(uuid.v6Ordered());

// UUID V6 timestamp
console.log(uuidToDateV6(uuidV6Ordered));
```
