Preserve global `node_modules` during reinstall about node-pi-zero HOT 2 OPEN

Hi Dave,

Thanks for the feedback but this is not something I'm not looking to implement at the moment.

Aside from the easy workaround (just reinstall them after upgrading/downgrading node), one can't just assume that global modules will work across node versions so its safer/easier to wipe them. The only other way would be to install each node version in its own directory and point the executable there instead, this is the way nvm works but I am not looking to rewrite nvm for the pi at the moment, too much work.

Hi Steven, my concern is primarily for the many newbies/hobbyists who will be using this. They will have a surprise waiting for them when they implement a small point upgrade from node 9.9.0 to node 9.11.1 and their global modules are wiped. There is no package.json they can npm install to reinstall the global npm packages. They must try to remember the 7 packages they installed globally after first experiencing the consternation of not knowing why http-server, for example, no longer works.

Once again, thanks for maintaining this repository. I use the NodeSource Repositories for my Raspberry Pi systems, but they do not support the Pi Zero (ARMv6 chipsets) so I have been using your solution.
