WIP: Deb upload, todos, and errata

The "repository" field doesn't have a type right now, so I'm going to
skip deserializing it. The returned JSON has a value for this field, but
Serde will ignore it.

The `Packages.pkg_type` field is called "type" in the JSON string (and
Go code, as mentioned in the comment). Similarly, the PackageType enum
I have to represent this field in Rust has capital starting letters
where the JSON uses all lowercase. Both problems are solved with a Serde
rename attribute.
