Extend options to allow empty arrays and ignored properties

[mikegirard]

When building responses for REST List responses, an empty array is significant. So extended options to allow them to pass through.

Also added support for a simple-minded excludedProperties to prevent omitEmpty from traversing/processing specific properties. (Just in case you want to exclude something from processing due to weirdness in requirements.

Any updates on this? I also have a similar use case. Thanks
