Overview
For imports in TS files such as:

import * as _ from 'lodash'

Typescript will now generate a quickfix to install @types/lodash if it is not already installed

Testing

1. In an empty folder with a package.json
2. In a TS file, write out a import for an npm package that you know has @types, such as express or lodash
3. On the import statement, there should be a quick fix for installing these types
4. Select this and confirm it installs the types, also updating the package.json if one exists
