Add Lovaflow app

[Krafting]

Hey, I've made Lovaflow, a simple application to manually control vibrating toys supported by Intiface Central using Buttplug.io. There are also a pattern mode that I will later expand with user-defined patterns.

It is free and open source, here is the source code: https://gitlab.com/Krafting/lovaflow-app

• It is available on Flathub (ARM and x86): https://flathub.org/en/apps/net.krafting.Lovaflow
• There is also an Android APK here : https://gitlab.com/Krafting/lovaflow-app/-/raw/main/release/lovaflow-android-latest.apk?ref_type=heads

Btw, I'm always looking for feedback on the app, issues, ideas, design, phrasing, etc... if anyone wanna report some issues, please do!
