v5

I developed v5 in Apr 2023. And I didn't get the chance to complete all the features. I've ensured that new features don't impact performance. With v5, you have more control on parsing output. Check docs for syntax help and basic understanding.

Please leave a comment in discussion forum for your suggestions and if you really need v5.
