feat: analyze a whole database and find its relationships [WIP] [Skunkworks]

[lerouxb]

I should probably change the interface to take all the schemas at once which should make it possible to check references to things other than _id. ie. make _id and every other objectid/uuid field that was selected as a candidate for any collection a possible target field. Although then you have the problem where if two collections reference a third one's _id, then those two would also be referencing each other. Which is not what you want 🤔
