AmbientAware isAlwaysOnScreen flag

[garanj]

WHAT

Adds support for selectively enabling or disabling always-on

WHY

Some screens will require always-on, but some will not, for example, a workout screen (yes) vs a workout summary screen (no).

HOW

AmbientAware now takes an optional parameter to specify whether the screen should enable always-on or not. This can be hoisted above the use of AmbientAware e.g.

AmbientAware(isAlwaysOnScreen == currentScreen.useAlwaysOn) { ambientStateUpdate ->

// ...

}

Checklist 📋

Really elegant approach. Nice!
