Subject: [PATCH] Add escape hatch for Series merging This is an universal
 solution for plugins to override how series are merged. The reason to
 override is so we can set the same provider id on multiple items without
 merging them, while using another id for merging them. Having an (optional)
 provider id not tied to any online database allows plugins to use their own
 rules for merging series.
