Prevent CSP in admin

First of all thank you for this awesome plug-in. I’m very happy with everything except I noticed that CSP headers (which are usually only sent in the front-end) are sent when on the page list admin page. This causes errors with some other plug-ins that use inline images and fonts (which are blocked by CSP). I would appreciate if this could be fixed so that CSP is only applied in front end. Thank you very much for your feedback.
