16.3.24 For Maintenance

This should be the final release of this customise firmware for BLLED
I've added all the functionality I wanted into this device.

• Finished print stays green until door opened/closed (when Finish Detection is enabled)
• Inactivity timer - turns lights off after 30mins (Customisable)
• Customisable Error / Finish / Pause colors (under the advance section)
• Add option to turn off having lights off during stages that would use lidar (eg for P1P owners)
• Added first layer inspection stage so lights are out during lidar when that occur (for those using X1C)
• Maintenance Mode just turns on the LED and ignores the printer (nice if you are working in the printer and it's powered off)
• Set Test Colors to verify the LED wiring
• Heavily filtered the MQTT to just the part important to BLLED.
