Supporting image compression formats passthrough (#1461)

Browse Source 
* Supporting ros depth compression formats passthrough

* Added image_compression_format (support jpg,png). Use Compression.h constants.

* Bridging gap with #1457

* CoreWrapper: decode_images_on_demand

* rgbd_sync->rgbd_split encoding/decoding test with image_transport validation. rgbd_split color passthrough

* more tests

* fixing ci on kilted+

* fixing test

* fixing lyrical tests

* fixing rolling ci

* Improved test coverage

* fixing some tf waitForTransform deadlocks when sim time is used in tests

* CI: build rtabmap_slam on rolling

rtabmap_slam builds without nav2_msgs, which is not on resolute yet: skip its
key instead of leaving the package out. Only rtabmap_costmap_plugins (and the
rtabmap_ros metapackage pulling it in) still need nav2.

Setting both is allowed and produces a message carrying each image twice, raw and compressed. That is rarely what you want.
Depth is compressed as **PNG**, a stereo right image as **JPEG**.
Depth is compressed as **PNG** by default (see `depth_compression_format`), in `compressed_depth_image_transport`'s format, color and stereo right images as **JPEG** by default (see `image_compression_format`), in `compressed_image_transport`'s format.
