Describe the solution you'd like
Lifecycle events can be added such as saving, saved, replicating, deleting etc to the package.

Describe how this would benefit the project/others
This would add an additional way to interact with the flow of the model logic.

Note: this will cause the event emitter to not to be tree shakeable as it's always included

Ideas:

• The listeners could return a boolean and if false the original logic stops e.g.: deleting hook returns false, no request will be made and and any further logic in the delete() method bot executed
• The hooks are free to change the passed in argument as it's passed by reference.

Describe alternatives you've considered
None
