Runtime Asset swapping

[schetle]

• RiveAsset class was broken into 3 classes
  • RiveAudioAsset
  • RiveImageAsset, contains runtime compatible functions:
  • LoadImageBytes (accepting an array of bytes in png, webp, jpg format)
  • LoadTexture (not yet implemented fully, as we wait on Rive to allow us to submit bitmap data)
  • RiveFontAsset, contains runtime compatible functions:
  • LoadFontFace (loads an Unreal font face, if the font face's load policy is set to Inline)
  • LoadFontBytes (accepting an array of bytes in ttf/otf format)
• RiveFile now supports a function "GetRiveAssetById", returning a base RiveAsset which can later be cast to one of the specific asset types to operate on
