Fix various problems with firework meta (de)serialization (#3905)

Browse Source 
Adds support for parsing fireworks charges (would previously cause exceptions due to illegal casts to FireworkMeta) and fixes createkit from producing invalid color values

Thanks to triagonal for reporting the exception caused by createkit.

Fixes #1283.
