Add filter for deduplication

[mslinnea]

Adds filter to allow custom logic for deduplication.

This looks good, but I have a couple questions/suggestions.
I wonder if we want to change the other returns in this section (lines 91, 98) into variable assignment and then have one filtered return of that variable at the end? This way the variable would filter all cases.
Either that or change the filter to wp_curate_default_deduplication_enabled or something like that, because this only overrides the default false value, not anything set in the block attributes or post meta. I wouldn't want someone to think they could filter all behavior and think it's not working right.
Also, I don't know what other changes you have planned, but the plugin will need a readme update and version bump so it builds a new version.

I'm going to update this as we discussed and then merge it first to the fam branch so that we can test it on our project before doing a release.
