Codeigniter 4 CSP don't support style-src-attr

Apparently, the CSP3 directives are not implemented in CI4.

It would be helpful if you could send a pull request to add the directive to the 4.5 branch.

Hi Kenjis, thank you for info.
You are right there is no CSP3 support in CI4.
I must implement other CSP headers too, like:
script-src-attr, script-src-elem, style-src-elem... 

Sorry but I have no experience with sending a pull requests to CI, and actually I have al lot of work
If you have a time please help me and send this request to add CSP3 support.

Sorry for my bad English. 
Thank you.
