I'm sure the CLI merge API is wrong :(

The design for CLI merge is:
```
openfn merge staging
```

Which will merge staging into the checked out project

But that's wrong right. Usually you've made changes on a branch, locally, to the expanded project. And you want to "push" those changes into some other sandbox. 

So its `openfn merge project-you-want-to-merge-into`.

So basically I think I need to flip it. And probably soon.
