Importing roku-deploy into a typescript project sometimes shows type errors because of a missing @types/request package. This is a devDependency, so it shouldn't clutter the production dependencies.

Also, we're only storing request on RokuDeploy to help with unit testing. However, we don't actually need to do that, since we can already stub/mock the request object as long as it's imported as import * as request from 'request'.

This might be a breaking change if any projects were utilizing the rokuDeploy.request property, but realistically that should have been a private property anyway, and there's an easy fix (import request in the host project...).
