[roseus_tutorials] add tf bbox sample

[shmpwk]

Add sample scripts which subscribe BoundingBoxArray and convert it to world coordinates.

You can quickly try this by launching sample_hsi_color_filter.launch.

• sample_hsi_color_filter.launch : launch hsi_color_filter.launch + pr2-setting.l + display-tf-bounding-box-array.l
• display-tf-bounding-box-array.l : main file (This is an extention of https://github.com/jsk-ros-pkg/jsk_roseus/blob/b8a4ba68aecfdcad8eacb836c2f6efe93c858d88/roseus_tutorials/src/display-bounding-box-array.l.)
• pr2-setting.l : read pr2 robot for display-tf-bounding-box-array.l, requiring pr2eus.

Note that when getting the base->cam-coords, we use lookup-transform .
This is because we expect base->cam-coordsis dynamic.
If your base->cam-coords is static, use (setq base->cam-coords (send (send *YOUR_EUS_MODEL* :YOUR_CAMERA_FRAME) :copy-worldcoords)))) instead.

TODO: make a sample for display-bounding-box-array.l with another PR.

To run this script, we need someone who publishes ~input_box. So , if this script used with pr2_tabletop.launch or tabletop-object-detector.launch please include this source code from these launch file. Please add display-bounding-box-array.l too if possible.
