[Feature Request]: Allow deletion of articles in omnivore

[windily-cloud]

Currently it is all articles can be synchronized to Obsdian, but this will lead to more and more articles in Obsidain, I personally tend to synchronize to Obsidian in the will handle, need Ominivore can also have the deletion and archiving operations.

I checked the api of Ominivore and it doesn't seem to be exposed, please tell me what's the best way to do it? I can do some contribution and testing on this side of Obsidian plugin, Omnivore I may not be able to help.

Also, I really like this app too much.
