capability for ngRedux to debounce the digests

The problem

In my huge app, I have a lot of stimulations that modify the store and each one lead to a digest (via $rootScope.$evalAsync). The accumulation of digests considerably affect the performance of the application.

Solution

We added a use of lodash.debounce in the digest middleware to avoid digesting too much.

Content of the PR

• add lodash.debounce to the dependencies
• Use of lodash.debounce in the digest middleware
• Creation of a config for ngRedux
• Documentation of the config
• unit test for the debounce
• Correction of a problem with redux-thunk in ngRedux.js

Use of the fonctionnality in my app

import angular from 'angular';

angular.module('ngapplication').config(($ngReduxProvider) => {
  'ngInject';

  // eslint-disable-next-line
  $ngReduxProvider.config.debounce = {
    wait: 250,
    maxWait: 500,
  };
});

last but not least

Thx for your usefull lib ;-)
