• [Common] Adds new MarqueeLabel types: Left and Right. These new types are non-returning scrolls, meaning they scroll in one direction (like LeftRight and RightLeft), but then do not ever return to the "home" position.
• [Swift] Adds the functionality to create custom scroll types using the scrollSequence property. The sequences can contain custom positions (between the basic home and away positions) at custom timings, as well as flexibility with edge fades.
