Feature Request: use "unknown" for unknown actors

[org0ne]

Releases often have unknown actors upon release, especially for smaller studios. I have typically used "unknown" as the actor name so that I can easily find all movies that do not yet have an actor name and then search http://sougouwiki.com periodically to see if someone has identified the actress.

Currently Javinizer just leaves the actor blank. While it is possible, searching for the "lack" of information is more difficult than using explicit searches.

Writing this out here just so it's documented:

New boolean setting sort.metadata.nfo.unknownactress added to add an "Unknown" actress to the aggregated data object if no actresses are available following the scrape.

The actress object will be output as follows, adding the name as 'Unknown' no matter what actress language preference is selected:

$aggregatedDataObject.Actress += [PSCustomObject]@{
    LastName     = $null
    FirstName    = 'Unknown'
    JapaneseName = 'Unknown'
    ThumbUrl     = $null
}
