Install script fails on windows

[hughboi]

I'm not sure if you intend on supporting windows, but I just thought I'd let you know this package fails when installing it into your project on windows.

It is a similar error to other packages that don't support windows. When running npm install or yarn install within your project on windows it throws the following error:

'scripts' is not recognized as an internal or external command," on windows.

The fix seems to be switching to a node script for running scripts/install.js as seen here. However looking at your install.js function, it probably would need some changes to be executable on windows.
