Improve 2D image generation and add benchmark tools

Enhanced the 2D image generation by caching backgrounds and optimizing counter placements. Introduced a new visualizer method for direct image sizing and added a benchmark script for drawing speed. Added a utility function for loading configuration files in bulk.

 ## [Unreleased]
 
 ### Added
+- 2D image generation speed ups. Cache background and basic counters, do other color dimension stacking.
+- Reduced background drawing. Only there where no counters stand (if you need that for moving counters you need to change it in the visualization.yaml)
+- Visualizer method for getting an image directly via the required image size (only squared images).
+- Added benchmark script for benchmarking the drawing time of the 2d visualization.
+- Utility function for loading/reading the config files all at once.
+- Get image size now returns an already transposed array (opencv style - not pygame style)
