MediaRSS + iTunes

The key change in this release is the support for MediaRSS and iTunes namepsaces and the subsequent impact on the model + element mapping, hence the bump to a new minor version.

Specifically:

• enclosure: the RSS spec states that <enclosure> "Describes a media object that is attached to the item." - https://validator.w3.org/feed/docs/rss2.html#ltenclosuregtSubelementOfLtitemgt
• content:encoded: RSS best practices state <content:encoded> "...defines the full content of an item (OPTIONAL). This element has a more precise purpose than the description element, which can be the full content, a summary or some other form of excerpt at the publisher's discretion." - https://www.rssboard.org/rss-profile#namespace-elements-content-encoded
• The MediaRSS and iTunes namespaces define media objects or attributes of items in the feed

Thus handling is as follows:

• enclosure is treated as if it was a MediaRSS MediaContent element and wrapped in a MediaObject
• content:encoded is mapped to the content field of an Entry
• MediaRSS elements without a parent group are added to a default MediaObject
• iTunes elements are added to the default MediaObject
