Bumping the version before merging a lot of changes, just to be safe. This version was tested by many people on our Discord, so should be more stable than current main.

• Rewrite of Sensor factory, LED manager, and configuration saving/loading by @TheDevMinerTV
• Fixes on ICM20948 and optimising @DemorianJH @ThreadOfFate
• Lots of code optimising in MPU6050 and MPU9250 by @doormatt-dev @LETS-BEE @deiteris @Timocop @TheDevMinerTV
• Changing default from POWER_SAVING_MINIMUM to POWER_SAVING_LEGACY @TheButlah
