Added
- Previously skipped, not-yet-released albums are now handled appropriately. In such
cases, `albumstatus` gets set to **Promotional**, and the release date will be a future
date instead of past.
Fixed
- Handle a sold-out release where the track listing isn't available, which would otherwise
cause a KeyError.
- Catalog number parser should now forget that cassette types like **C30** or **C90**
could be valid catalog numbers.
Updated
- Brought dev dependencies up-to-date.
