A new manual for installing ROMS on Mac OS

[osean]

Having gone through a rather tedious process of setting up ROMS, I think a new manual for installing ROMS on Mac OS would be extremely useful, for someone like me who is new to the modelling community and has very little clue what is going on, especially since the ROMS Mac page on WikiROMS is very outdated. For example, the build.bash file has been changed to build_roms.sh, and the path file is now separate as my_build_paths.sh, and even the output is now romsS instead of oceanS... a lot of changes that can be hard to follow! Thus it is very easy to get completely lost by following the wiki page.

I put together a document based on what I did - including how to avoid downloading the now very cumbersome Xcode 12 etc. - I hope this can be helpful to anyone else who is going to be using Mac for ROMS.
