Add internal quantum numbers for several mesons

[eduardo-rodrigues]

These are updates to the extended particle information, the one that the PDG only provided in their 2008 extended data file. These internal quantum numbers are becoming more and more used by analysts it seems, hence it makes sense to add info manually. As this is extra info, not an actual particle data (measurements) update, I kept the version and date of the data file.

Closes #486 and #616.
