Feature Request: install a custom local build of nodejs

[kumavis]

First: I love nvm, its amazing, I use it all the time. :smile_cat:

I'm experimenting with building forks of nodejs. I'd like to be able to add these builds to nvm's locally installed versions.

here's what I imagine the usage looks like

nvm install-local 'xyz-v1.0.0' ./out/Release
nvm which current
# ~/.nvm/versions/node/xyz-v1.0.0/bin/node

I'd expect it to copy the built release so that it doesn't change when I rebuild. I don't have strong opinions about how the version number works.

Is this currently possible? if not, does this seem reasonable?
