Pre-release of underlying refactor

This is a pre-release of a pretty major refactor. Instead of tracking component requirements through their lifecycle, this release depends on the re-render of connected components to update requirements regularly. See #203 for details.

v0.5.0 pre-release - @wordpress/data compatibility

This release adds compatibility for @wordpress/data in the form of functions on the ApiClient class:

• getSelectors( componentReqirements )
• clearCompoentRequirements( component )
• setCompoentRequirements( component, componentRequirements )

These functions allow roughly the same behavior as setComponentData before, but better integrates with the flow of @wordpress/data's select functionality.

0.4.0 release - Simplified api spec

This release simplifies the API spec given to fresh-data.

It removes the methods in favor of just pre-loading operations with the methods needed.

Additionally, this version changes the license from GPL v2.0+ to MIT for broader application usage.

0.2.0 Release - API updates

Changes affecting apis using fresh-data:

1. Instead of ( getData, requireData ), selectors are now given
   ( getResource, requireResource ). Both of these functions return the
   state of the resource by its given key.
   a. getResource( resourceName ) returns resource state in the format
   of { data, error, lastReceived, lastRequested, lastError }. All
   properties of that state are optional and may not be present, but
   getResource will always return an object, even if it's empty.
   b. requireResource( requirement, resourceName ) sets a component
   requirement for the given resource, and then returns resource state in
   the same manner as getResource.

2. mutations now return proper promises, which can be used to handle
   success and failure callbacks via a Promise resolve/reject, or by
   using async/await.

3. Within the client class, methods, operations, mutations, and
   selectors are no longer static members, but members of the object
   instance. This provides greater flexibility in API implementation by
   allowing things such as passing methods in via a constructor.
