[Feature request] Portrait Mode / Blurred Background

[xeruf]

You have a long list of Features that I would not even call features but basic functionality: https://github.com/iakmds/librecamera#features

As a user, I want to know what the app can do for me, and different photo modes make a world of a difference - I noticed that now as my Lineage 19 Fairphone 3 is so far lacking any of these modes, and have seen the quality other phones make, which is often in big part related to the software.
