Configuration
Not really a plugin type: A reuseable '.parcelrc' package
This is simply a .parcelrc file wrapped into a published package, the main points to the config file.
{
  "name": "parcel-config-foo",
  "main": "index.json",
  "version": "1.0.0",
  "engines": {
    "parcel": "2.x"
  }
}One usecase for this is a system with multiple plugins.
