Add Immersive mode

[M1ckB]

On my Boox Onyx Go7 (running an Android 13 flavor), I'm unable to use Capy Reader in fullscreen mode:

I would expect Capy Reader to use the entire canvas, like it does on my phone. Other apps are able to show fullscreen on the mentioned device.

Let me know if you need anything else to debug the issue.

Hey @M1ckB, when you say "show fullscreen," do you mean that the top and bottom bars slide away? If you have any other apps that you can share that do this well, let me know!

Hello, @jocmp,

Yes, that's exactly what I mean. Since the device doesn't have a dark mode, it's really hard on the eyes with the big contrast.

I'm using Readest that does this really well. Let me know if you need more references.
