[Request] Option to apply an overriding stylesheet

[anthonyajumelles]

I like to read fan translations of foreign books. However the issue with a lot of these projects is they tend to be written in Google Docs which, when exporting to epub, doesn't produce a file that respects Foliate's font setting for

.

I'd love to be able to use any of the default CSS stylesheets from browsers implemented or KOReader's default CSS stylesheets, over each epub's individual CSS implementation. This should address some of the visual issues with inconsistent font sizing that users are reporting.

I think this is actually the same as #947.
