Include separate rules for Director etc.

[TC-75]

As well as the generic and flexible 'people' filter, have some specific filters for Director etc., that use the built-in Jellyfin metadata. At the moment with a large library creating a collection for (e.g.) Fellini as director takes 20-25 mins to complete (vs seconds for other rules). But the otherwise much simpler AutoCollections plugin can complete the task in seconds, I think because it is using the 'standard' metadata for each film, rather than a more powerful search. The same could potentially apply for other people fields (writer, producer), although maybe not cast.

Hmm from earlier experience, all people metadata (including director etc) are slow to lookup. It's interesting to hear that AutoCollections does this fast though. I'll look into this and see if there is indeed a faster way to lookup people metadata.

I checked quickly and it does seem like Jellyfin exposes a prefilter option that I was unaware of. I'll go ahead and include this in the next release, this should have a major performance boost on many of the people metadata lookups. I'll look into if there are other prefilters to use as well.

Fixed in RC v12.0.0.17. Try it out and let me know how it works.
