DESCRIPTION OF CHANGES:

This small PR modifies the export statements for LD_LIBRARY_PATH from appends to prepends in workflow/sideload/launch.sh. This makes the libraries built with RDASApp take precendence over any libraries loaded as part of spack-stack. In particular, this allows us to load the larger jedi-mpas-env bundle that includes gsibec while still using the gsibec libraries built inside RDASApp.

This was tested and merged in the RDASApp here.
