Add support for real-time models

[Affonso-Gui]

• Update the detic submodule
• Add model_type option to select different real time models (https://github.com/facebookresearch/Detic/blob/main/docs/MODEL_ZOO.md#real-time-models)
• Add use_jsk_msgs option to publish the result as jsk_recognition_msgs types
• Add sample launch file of 3D object detection using the jsk_pcl_ros pipeline.
• Remove explicit background item from published topics for compatibility with jsk_recognition nodes.

With this I could get around 10Hz bounding box detection on the res50:

roslaunch detic_ros sample_detection.launch vocabulary:=custom custom_vocabulary:=cup,bottle,bottle_cap
