Pokemon Generations Issue

[FM1337]

It was brought to my attention in this GitHub issue FlagBrew/PKSM#1363 that a Pokemon converted from Generation 2 to Generation 7 format (file size is consistent with Generation 7) is labeled as Generation 2.

an extra data field might need to added to show current generation to distinguish between original and current generation for the sake of data consistency and compatibility

This will be mostly fixed by #12 but will need some updates on the FlagBrew site's repo to take 100% effect (plus will need to run data migrations >_<)

I think I can finally close this.
