Natural increase and decrease of temperature/gamma

[sand4rt]

By default hyprsunset uses a linear scale for temperature/gamma control. However, according to the Weber–Fechner law, human perception of sound is approximately logarithmic (base 10), not linear.

I recently submitted a pull request to Hyprland to make brightness adjustments align more closely with human perception. It would be great to see a similar feature in hyprsunset—perhaps an option like -e{number}, as found in brightnessctl:

-e, --exponent[=K]		changes percentage curve to exponential.

I also think it would be a great improvement if temperature/gamma changes were smoothly transitioned to the new level—similar to the behavior requested in this open brightnessctl issue: Hummer12007/brightnessctl#26 (comment)

Huge thanks for Hyprland and Hyprsunset btw!

For graduated transition you can currently use sunsetr but ofc build-in support would be great.
