Unit/Integration tests for AWS Lambda handlers

# Change Log

## 4.0.1 (2019-12-04)

Update:

* Remove note about Node version check in documentation. Thanks @munierujp

## 4.0.0 (2019-11-23)

Breaking:

* Strict checking for how the results/errors are captured have been relaxed. this
  can be re-enabled using the `strict()` method after creating the `LambdaTester`
  instance.

* Node.js versions are no longer checked before running the tests.

New:

* Event mocks (via `lambda-event-mock`)

Updated:

* `expectResult()` and `expectError()` are now the preferred methods to verify
  the handler's execution. If strict mode is enabled, then it will enforce that
  the callback is called.

Internal:

* Updated dependencies
