Cam2map missing projection info when using PROJ

**ISIS version(s) affected**: ISIS 10.0.0RC2

**Description**

When running cam2map on an image, the output image does not contain any projection information when using GDALINFO.

**How to reproduce**

run cam2map on any image using the proj features, then run gdalinfo.

**Possible Solution**

We probably have to explcitly call setprojection. Consider only enabling this for non-cubes. e.g. GTIFFs. I imagine cubes would require a sidecart file. In the cube case, we might need to update GDAL to read the proj string.
