Add support for project references

What happens and why it is wrong

Since typescript 3.0, typescript has added support for project references. tsc -b now build all projects listed in references section of the main tsconfig before the main project is built. See typescript documentation for project references.

When using rollup-plugin-typescript2, the references projects are not being build at all. It only builds the current project.

Partial support is in 0.20.0 now.

What does it mean partial? I’m trying to use this feature in a monorepo and I don’t get my referenced package rebuilt when I add the option in the plugin conf or in my tsconfig…

    typescript({ build: true }),

...
  "compilerOptions": {
    "declaration": true,
    "declarationDir": "./dist",
    "module": "es6",
    "noImplicitAny": true,
    "strict": true,
    "outDir": "./dist",
    "target": "es6",
    "sourceMap": true,
    "build": true
  },

Composite flag is on in my referenced package and running tsc --build works as expected

Am I missing something?
