Allow vertical orientations

[weegeekps]

Requested from: https://www.reddit.com/r/ExtraLife/comments/joagvc/a_simple_alternative_overlay_for_your_stream/gb7dmu6/

cherry_pibb on Reddit requested the ability to orient the bar vertically, rising up from the logo. Seems like a natural progression of the orientation system, and should be investigated.

Tasks

• Implement vertical going up.
• Implement vertical going down.
• Tests
