Updating and adding of various crest URL

[JianLoong]

This issue is related to #44

The flag URL has been fixed however, the "crest_url" which points to the Wikipedia website entry has not been addressed.

For example in the file state/v1/johor.json the

"crest_url" information is currenty

"https://en.wikipedia.org/wiki/Johor#/media/File:Coat_of_arms_of_Johor.svg"

when it should be instead

"https://upload.wikimedia.org/wikipedia/commons/thumb/6/60/Coat_of_arms_of_Johor.svg/1280px-Coat_of_arms_of_Johor.svg.png"

This is the same as several other entries.

Missing crest_url from other states should also be added to handle this issue.
