lrose install Python 3 compatibility for MacOS

[nguy]

I recently installed lrose from binaries, specifically lrose-20180430.bin.mac_osx.tgz. I found that the install_bin_release.py worked with Python 2, but not Python 3. I ported this over to allow installation using Python 2 or 3 and thought it might be of interest for others. I'm not sure where this file exists, so I'll paste here for now. If you would like a PR, point me to the directory where this is stored.

Hi We are working on testing out LROSE on the Windows Linux sub-system, but so far we have not succeeded in getting it to install and run. Mike
