Was having problems with running some of the other diagnostics on my mac, so I added some lines similar to what is in the get_ss3_exe() function in r4ss to be able to tell the exe to use by some of the system info from R.version (this will be updated to include the arm64 mac version too).
M2 chip/arm64 architecture for macs seem to need their own executable that doesn't have backward compatibility for x84_64 architecture, an arm64 version of the ss3 exe
Fix the par file that profile_multi is looking for since all the linux and mac exes are ss3_linux or ss3_osx and need to get rid of the _linux or _osx to get the right par file name
ss3_linuxorss3_osxand need to get rid of the _linux or _osx to get the right par file name
