Allow dispatching of Platform and Generic Events about salesforce-rest-sdk

So Platform events are easy peasy. Already supported actually. Just create them like a regular SObject!

    'SomeField__c' => 'SomeValue'
]);

$sObjectClient->persist('MyPlatformEvent__e', $event);

The example above, the $sObjectClient is an instance of SObjectClient
