Event class missing the organizer_email and organizer_name attributes

[jmarchello]

Describe the bug
The API documentation, as well as a test of the API via REST, demonstrates that when querying an event, two attributes of the Event object are organizer_email and organizer_name. Unfortunately, these attributes are not parsed and provided by the SDK at this time. The only other way for me to get the organizer email is to parse it out of the owner attribute.

To Reproduce
Some steps involved to reproduce the bug and any code samples you can share.

# Query the event
event = api.events.find(event_id)

# attempt to access the organizer email
event.organizer_email. # This will result in a NoMethodError 

Expected behavior
The organizer_email method should return the organizer email address as a string

SDK Version:
5.15.0

Additional context
It doesn't look like the master branch contains this attribute either, from what I can tell.
