[Feature Request]: Add Open Source PipUp Android TV Notification integration

[suredesigntshirts]

Describe what you are trying to accomplish and why in non technical terms

Attempting to get TV alerts working with this blueprint. I've attempted to install the required apps for my Android TV Box, but they do not support my Android TV Box.

I've found this app PipUP which is available for my for TV Box and is open source. It's older, but seems to work fine on my TV.

Describe the solution you'd like

Alternate alerts using Open Source PipUp app. Instead of closed source current implementation.

Describe alternatives you've considered

Notifications for Android TV app is not available for my TV Box. Nor is it open source.

Notify Android/Fire TV devices using https://www.home-assistant.io/integrations/nfandroidtv/

I think the above apps only support Android 11 and my device is Android 10.

The device is some cheap android TV box my cable company provides for watching TV on my fiber line.

Additional context

Android App: https://play.google.com/store/apps/details?id=nl.rogro82.pipup

Discussions / Docs:

• PiPup - Android TV app for notifications
• A short guide for setting up TV PiP notifications (with PiPup)
• Tech Docs - Real-Time Picture-in-Picture Camera Feeds on your TV with Home Assistant

Bug Fix In the Blueprint header documentation, please link to and explain that for TV Alerts to work, you need to install https://www.home-assistant.io/integrations/nfandroidtv/

While you can find this information, it's not in the blueprint header docs and if it was, it's easier UI/UX for users to understand how to get this TV implementation working.

I looked into pipup previously and figured sideloading apps would be more troublesome for a lot of people.

For the record i have a fairly old budget android tv which definitely wont be on android 11 and the app is available.

I will give it a go when i can.
