Forked this package and Refactored with typescript

I forked this Package

https://github.com/cthulhu-oidc/license-generator

benchmarks:

```
parse x 29,870 ops/sec ±2.12% (90 runs sampled)
parse (cached) x 264,048,849 ops/sec ±1.04% (94 runs sampled)
generate x 1,262 ops/sec ±0.80% (94 runs sampled)
```

I did not publish it yet. Maybe I add the date expiration handling to it.
