Release editor seeding is incomplete

For example:

• It's a pain to seed things like secondary type
• It's also impossible to auto-add the created release group into series
• It's painful to determine field names because they don't match the editor
• There's no way to say a release lacks a barcode
• There's no way to say a release's tracklist is not known
• It's painful to continue to adding cover art and extra relationships

I solved it by puppeteering my browser and it's super hacky, I don't think it should be like that and MB could make it much easier to create a full release group with the relevant data.
