Private Properties Support

[bradennapier]

It would seem that private properties is not yet supported by this plugin.

Works

class PubChan {
  #pipeline;
}

Doesn't Work

class PubChan {
  #pipeline: {};
}

update interestingly, it would appear the React eslint plugin adds support for this as I can add this on any react projects but not on my others using just flow & proposal-class-properties.
