feat(iOS): Setting/toggle to enable "Show RPC" turned on default

[SerStars]

A setting or just on default, the "show rpc" toggle should be turned on default. And let's be honest, why else would people install the app? It's just a extra step.

It's also a battery drainer having the app constantly in the background.
#36 would be a possible solution.

I meant like when the app is opened by the user and it starts running the rcp when there's music playing
