Not all product info meta URL is the same #4

Currently the product info meta URL is hardcoded to:

http://dl.stickershop.line.naver.jp/products/0/0/1/{}/android/productInfo.meta

from which {} will be replaced by sticker ID. However, some stickers, such as the one with ID 884, has product info meta URL of:

http://dl.stickershop.line.naver.jp/products/0/0/12/{}/android/productInfo.meta

there are still other different ones besides 12. However, I haven't figured out how to get that number or even simply knowing what it means. As a silly workaround, you might want to retry up to some reasonable constant (25? 99?), except if you already know how to get that number of course.

Yes, I've noticed this problem a while ago. I believe it's not just the second to last number that can be different for some stickers. Older sticker sets had slightly different product metadata, and the URL could be a able to "version" the different formats.

I'm thinking of eventually adding an offline database function to the script, and it'd be an interesting opporunity to get a detailed look at what causes the different URLs. I haven't really seen a pattern to the numbers either, so any failed downloads that result from this have to be looked at on a case-by-case basis as issues come up. Alternatively, one of these days I just start at sticker pack 1 and increment all the way up to the current number, but I don't think there are enough exceptions that it'll be necessary.
