Add Canton Mint

Hi all, I think we should add the Canton Mint. This is the site that is responsible for the late 19th-early 20th century strike of the Guangdong/Kwangtung and some other provisional milled cash, copper, and silver coins. AFAIK this is not the same as Guangdong mint or the other government branches that are listed on the site. Closure should be at 1931.
