Bug fixes to address incorrect handling of RADIUS in the jigsaw GUI and in the bundleout.txt file when performing a rectangular (XYZ) bundle adjustment, originally implemented in UofA OSIRIS-REx code on 2019-07-30. Addresses #5642. (#5643)

* The RADIUS checkbox in the GUI is excluded when a RECTANGULAR solution is selected.

* In the bundleout.txt file, for rectangular solutions, 1) RADIUS is set to N/A in the SOLVE OPTIONS section; and 2) the POINTS UNCERTAINTY SECTION was fixed to properly display adjusted point uncertainty statistics with Error Propagation turned on.

* Spacing for point labels was cleaned up in the INPUT: GLOBAL IMAGE PARAMETER UNCERTAINTIES section.

* Finally, a slight modification was added to the FunctionalTestJigsawBundleXYZ ctest to verify that RADIUS is N/A in a RECTANGULAR solution.
