Anything the reviewer should know when reviewing this PR?

Camera configs without an _about section remain supported. The log is opened in append mode, so the metadata appears at the start of each run’s log output, not necessarily at the top of an existing log file. All repository references to the renamed and removed workloads have been updated; no compatibility break is expected.

Test Instructions if applicable

From performance-tools/benchmark-scripts, run these three test cases

python -m unittest
stream_density_test.Testing.test_get_camera_config_about_reads_selected_config
stream_density_test.Testing.test_print_camera_config_about_shows_selected_config_and_fields
stream_density_test.Testing.test_print_stream_density_report_summary
stream_density_test.Testing.test_pipeline_iterations
