Include Crameri and Proplot colormaps.

- Don't move the center point when zooming in or out at max/min distance respectively (fixes infinitely scrolling cube)
- Do not force data aspect ratio in widget mode - fixes bugs with initializing widget with 100x500 (XY) data sets and similiar
- Bump to v0.4.15
