  Description     : Node.js module to manage optional peer dependencies

require_optional is a work around for the lack of optional peer dependencies
in Node.js.

Note that there is also another "require-optional" in npmjs.com. This one is
the most popular and the most downloaded. It is also a dependency of
official mongodb driver (node-mongodb-core, #897361).
