Rewrite the entirety of the Ambilight module for better functionalities
and performances. I wrote an advanced algorithm to get a smoother result
in addition to more parameters :

• device_index
• edge
• reversed
• band_depth_percent
• weight_exponent
• sample_overlap_percent
• saturation_boost
  -temporal_smoothing_tau

The main functionalities added are:

• Advanced Color Averaging: Improved methods to calculate smarter average colors, such as sampling larger color bands or allowing LEDs to influence adjacent colors.
• Temporal Smoothing: Introduction of “temporal_smoothing_tau” to ensure smoother, more natural color transitions over time.
• Enhanced Immersion: Addition of “saturation_boost” and “weight_exponent” parameters to deliver a more vibrant and immersive visual experience.

For instance, the colors on the left terminal simulate the final result that would handle the left edge of the screen (using default parameters).
