added thermal camera tutorial

[adlarkin]

I've moved the thermal camera sensor tutorial over from osrf/ign-gazebo to this repository since it's a sensor tutorial.

Depends on gazebosim/gz-sim#442.

When I was writing this tutorial originally in osrf/ign-gazebo, @iche033 recommended that I use @image to get images uploaded to the ignition robotics website (relevant comment here). This seemed to work fine for me in osrf/ign-gazebo, but for some reason, the images don't seem to render using @image with doxygen when I test this tutorial in osrf/ign-sensors. Can someone else test this to see if the tutorial appears correctly for them on the ignition robotics website? And if it doesn't work for anyone else, why would @image only work in osrf/ign-gazebo?

You need to add these lines here:

Review comments have been addressed, and image/example code display issues in the tutorial have also been resolved. I believe this is ready for final review.
