[Feature] Return data from referenced fields, rather than just an item ID

[tomelliot]

Return data from referenced fields, rather than just an item ID.
Currently getting data out of a CMS item that has referenced fields requires lots of lookups

• what field has the reference
• what CMS is being referenced
• what item do I need from that CMS
• what field do I need from the referenced CMS item

It’d be great if Get Collection Item (on the original CMS item) just returned the referenced CMS item as a nested object, or there was a function in the library that took in the reference field from the original CMS item and returned the object from the referenced CMS.
