This commit adds the RH/ZO perspective function. It does so in the new file `cam_rh_zo.h` and further refactors the LH variant into new file `cam_lh_zo.h`. This creates some churn in the tests and configuration files as new test files were added as well, and all these changes found their way into the build files. Tests passing on Linux.
