Merge proto files from multiprocess run into one file. (#63)

- Added script to merge multiprocess output automatically to one file when there are multiprocess proto files written into output folder
- Execute the merge multiprocess script from the rank 0 process
- Added the scripts folder path to env path, via setup-env.sh
- Installed merge_multiprocess_output.sh to /share/rocprofiler-systems/bin dir
