Slice.Origin is not being set

[AristurtleDev]

Description

When any of the processors create a Slice object for a TextureRegion the constructor of the Slice class takes in the Origin as a parameter but the value is never set for the property.

Steps to Reproduce

1. Import an Aseprite file that contains slices with pivot data
2. Use the TextureAtlasProcessor or SpriteSheetProcessor to process the Aseprite file

Expected Behavior

The Slice.Origin value for any Slice element in any TextureRegion to contain the data from the slice's pivot data in Aseprite.

Actual Behavior

All Slice.Origin values are defaulted to Vector2.Zero

Configuration

Not Applicable

Other Information

This is occurring because the Slice.Origin value is never set in the constructor.
