This commit adds Nexus test case 1.2.LP.5.3.6, which validates that a Router can support a child transitioning from a Synchronized Sleepy End Device (SSED) to a Minimal End Device (MED) and back. The test procedure involves: - Forming a network with a Leader, DUT (Router), and SSED child. - Verifying SSED attachment and initial CSL-based connectivity. - Transitioning the child to MED mode and verifying the corresponding MLE Child Update exchange and connectivity. - Transitioning the child back to SSED mode and verifying that CSL synchronization is resumed. Changes: - Implement tests/nexus/test_1_2_LP_5_3_6.cpp for test execution. - Implement tests/nexus/verify_1_2_LP_5_3_6.py for pcap verification, with logic to distinguish between synchronization and polling Data Requests. - Update tests/nexus/CMakeLists.txt to include the new test. - Update tests/nexus/run_nexus_tests.sh to add the test to the default test list.
