SpriteComponent's Reversed property cannot be set externally

[AftrLite]

I was asked to make this issue by @moonheart08 .
The field in question:

• [ViewVariables] public bool Reversed { get; internal set; }

Allowing this field to be set externally would allow users to let sprite layers' animations play in reverse, which would be an optimization under several use-cases as it would remove the need for a seperate sprite animation of XYZ playing in reverse, and thus also reduce sprite atlas usage.
