chore: bump version to 3.2.1dev0

[terriko]

This changes our working version number to be 3.2.1dev0 so you can easily tell if you're running the release version or working on the development tree. (The next release will either be 3.2.1 or possibly 4.0 depending on whether NVD removes access to NVD API 1.0.)
