Description of Change

New Example: Zigbee Multi-Switch

• Implemented theZigbee_On_Off_MultiSwitch.ino sketch, which includes:
  • Configuration and control of up to three Zigbee lights.
  • Persistent storage of light configurations in NVS.
  • Serial command handling for light control, network management, and factory reset.

Enhancements to Zigbee Core Library

• Added a new APS data indication handler to process bind/unbind requests and update the bound devices list dynamically.[1][2]
• Introduced acloseNetwork method to complement the existingopenNetwork method, allowing for better network management.
• Enhanced the Zigbee application signal handler to handle device updates for routers and improve endpoint binding logic.[1][2]
• Added a_debug flag toZigbeeCore for enabling detailed logs during development.

These changes collectively improve the functionality and usability of the Zigbee library while providing a new example to demonstrate its capabilities.

Tests scenarios

Tested using 7x ESP32C6 (1 piece loaded with the new MultiSwitch example as Coordinator or Router, 6 pieces loaded with On/Off Light example).

• When MultiSwitch acted as coordinator, all lights were able to join. and bind to the switch and can be controlled
• When MultiSwitch acted as a router, it connects to a network running in HomeAssistant (ZHA), and when I bind all 6 lights that were also connected, I was able to control them.
