merge field_types of fullcalendar_view_processor plugins

Please review the MR !69

Thanks @Matthias for reporting it and the MR.

I identify another issue, maybe, with the following line in that commit.

https://git.drupalcode.org/project/fullcalendar_view/-/commit/91125f112d...

I think the comparison should be changed to

if ($start_field_option['type'] === $fieldtype) {
  $valid = TRUE;
  break;
}

Here is the patch for the MR.

https://git.drupalcode.org/project/fullcalendar_view/-/merge_requests/69...

We need someone has the Smart Date module or any other module that implements the fullcalendar_view_processor plugin installed on their site to test and confirm for us.

So I will leave it as 'Needs review'.

@Mingsong thanks you for the review, sorry for the late response.

I have reviewed your changes and think they should be reverted, see the comments in the MR.

Maybe it is possible to add an integration test with smart_date. I'd like to give it a try.
