A simple picture frame with rounded corners, heavily inspired by the media frame widget.

## Supports:
- Multiple images
- Singular images
- Configurable delay between image changes
- SVG and Transparent background images

This widget does not have a background and the transition animation has been adjusted to be more suitable to images of different aspect ratios without there being an overlapping effect.

Known Issues:
1. Initial transitions don't work as expected. This should clear up with consequent transitions
