html2text and licensing

[ineersa]

Hi.

I was checking html2text usages to get more tests for my port for it and noticed that you got it in your codebase,

Also I've noticed that crawl4ai is licensed under Apache license, but original https://github.com/Alir3z4/html2text is licensed under GPLv3.

GPlv3 is pretty restrictive and requires proper attribution, so I wonder how you were able to re-license it as I want to do similar for my port too, as it moved quite a lot now from original implementation.

Thanks.
