Title: Add Configuration Options for Customization

Description:
Introduce user-configurable options to increase the flexibility and usability of the library. This will allow users to tailor the behavior of the heatmap generation and visualization to their specific needs.

Suggested Tasks:

1. Heatmap Color Schemes:
   • Explore the feasibility of adding additional color scheme options for heatmaps.
   • Note: Implementing new color schemes would require significant updates to the algorithm that converts normalized heatmap float values to RGB color hex values. This is a complex and resource-intensive task, making it unlikely to be implemented in the near term.
2. Board Orientation:
   • Allow users to flip the chessboard to view it from a specific player's perspective.
3. Highlighting Thresholds:
   • Add options to configure thresholds for highlighting specific moves or patterns.

Acceptance Criteria:

• Users can configure board orientation and highlighting thresholds.
• Heatmap color schemes remain under consideration, but complexity is documented clearly.
• Documentation is updated to explain available configuration options and usage.
