v0.4.1

Changelog

• Added support for Bevy picking under the picking crate feature (enabled by default).
  • Added a new picking example.
• Added a new all example which combines all other examples. Which allowed me to test how different parts of bevy_smooth_pixel_camera work together.
• On an completely unrelated note: Fixed sprites in the high resolution layer not rendering when HighResolution is enabled.
• The viewport texture now lives exclusively in the render world, where previously it was wasting memory while being all zeroes.
• Slightly slowed down PanCamera movement in examples from 20.0 to 15.0
• Miscellaneous code improvements.
