v4.7

Hi! Welcome to another release of Clight!
This releaase cycle was quite short but it brings lots of goodies!
Let's start!

Features

• Keyboard backlight is now specified as a curve for AC and BATT states, just like screen backlight
• Geoclue GetClient call is now async to avoid "freezing" for 20s waiting on geoclue daemon to answer on startup
• Dbus API does now expose MonitorOverride api

Improvements

• Stop Gamma module where not supported
• Added a timeout of 30s for waiting on geoclue; if no location is received, kill Location module (it avoids weird situations where there is no cached location and clight awaits forever for geoclue to give a location)
• Improved geoclue error handling with meaningful messages
• Deregister modules instead of just stopping them where unsupported/in case of init errors, so that they won't waste resources
• When a module is deregistered, its bus api is killed too
• Plot backlight curves directly using fit parameters instead of using x and y loaded from config (makes much more sense)
• Plot backlight curve for any curve (backlight, monitor_override and keyboard), but only in verbose mode

Fixes

• Fixed a memleak: properly free monitor override map
• Fixed curve data points validation for custom module requests

Configuration changes

• Dropped keyboard.ambient_threshold as it is now superseeded by new keyboard curve
• Added keyboard.ac_regression_points and keyboard.batt_regression_points

As always, I hope you will enjoy this new release!
