lato_install doesn't install Lato in macOS and Win10

[ajjitn]

Instead it imports current system fonts and then outputs an error message saying Lato font isn't installed, please install and try again. The workaround is to go to Google: https://fonts.google.com/specimen/Lato, download and install the .ttf font files, and then rerun lato_install. I think we should at least have some more specific instructions for Win10 and macOS users on how to install Lato by themselves.
