deepstream-sahi

Rebuild and test the SAHI C++ plugins / nvinfer parser after editing them. Use when changing gst-nvsahipreprocess, gst-nvsahipostprocess, or libs/nvdsinfer_yolo, and you need to verify it compiles and the result is correct.

Run / benchmark a DeepStream-SAHI model the user picks (FPS, per-frame detections, optional annotated MP4). Use when asked to "test a model", "run the SAHI pipeline", "benchmark <model>", or compare models.
