Decode HTML entities

The patch in #4 worked for me, but it took a while for me to figure out that this will only work when the export is set to "batch" mode.

Perhaps if this is approved it should have a disclaimer for this in the configuration description.

darren oh → made their first commit to this issue’s fork.

The problem also occurs when using a "REST Export" display and selecting "Data export" as the style.

render() in Drupal\views_data_export\Plugin\views\style\DataExport uses core's serializer so I guess ultimately the problem should/could be fixed there, but it would be useful if this module supported the option to decode HTML entities.
