We'll look into this, thanks for pointing it out @sjpotter

Another thing to think about, if one wants to go full into this, approaching the go struct / json mappings to mimic how python itself generates metadata.json from the METADATA/PKG-INFO files.

edit: In practice, I dont know why python does something significantly more complicated than the simple mapping you guys did, but it does :/. Not sure if its worth it to try and make them compatible, but at least something to think about.

Looks like 2.3 metadata isn't supported either. Maybe an error should be bubbled up when an unsupported metadata version is present.

opened #38 to address my second point here
