2.0.0-rc.1

New features

• Implement decorators from ember-concurrency-decorators (#386). The "nice" decorators
  from ember-concurrency-decorators are now built-in to ember-concurrency, without
  requiring an additional addon or seperate import. All decorators are available for
  import directly from the top-level ember-concurrency package.

  Many thanks to @buschtoens for years of stewardship of that addon, and important contributions from @chancancode for TypeScript support, and others in the community to get it to a place where it's seen wide adoption in the world of Ember Octane, TypeScript, and native ES classes.

  Addon maintainers: Please see notes in UPGRADING-2.x.md if you're using
  decorators currently, and wish to support both ember-concurrency 1.x and 2.x at
  runtime.

Documentation

• Rewrite documentation to use native classes and decorators, and update tutorial
  to show rewriting of async function code, rather than Promise code, as is more common
  today (#387, #389)
