Save the volume level

[tomas-barros1]

Every time I open the app, the volume is reset to 100%. It would be great if the application could remember the last volume level used and restore it automatically on the next launch.

That would be a great first issue to contribute to, the volume could just have its state saved in the config :)

Dabbling on rust for the past few weeks, I will try this out

It saves the volume level for me on Windows 11 (Home) even after restarting.
