#3119 (the base of this branch) is merged. Conflicts with the Cryptomatte
import (#3109) and the version report: Extra keeps Extractor, Identifier
and Cryptomatte, arbitrary.rs keeps ExtractorChannels /
identifier_channel_type next to CryptomatteData, the effect table counts
66, the docs keep both sides. The exporter from #2594 gets the Extractor
and Identifier arms: like Lumetri they have no prototype, so CC Color
Neutralizer, EXtractoR and IDentifier are reported, not written (new
test imported_plug_in_effects_are_reported_not_written).
