[Feature Request] Add the author element to the fulltext feed (when specified on the original feed)

Hello,

Using this script, I noticed the author of an article is not set on the fulltext feed, even if this information is on the original feed.
I would greatly appreciate to see this added, when it exists on the original feed, on a future release.

Here is the missing tag on an RSS feed :
<author>...</author>

Sometimes replaced with : <dc:creator>...</dc:creator>
The creator element is from the Dublin Core Metadata Initiative.
Here's the schema: https://dublincore.org/schemas/xmls/qdc/2008/02/11/dc.xsd
This element is seen all the time on feeds associated with WordPress blogs. It has become popular and generally preferred over the author element because the latter requires publishing an email address. The format for the creator element content is less restrictive and usually is just a name or username/handle.
