feat: multi region

[djdembeck]

Couple of things to think about:

• [x] Should metadata.id use region codes? IE, B017WPKX84 -> uk-B017WPKX84. This would be a breaking change.
• [x] Write a region override, similar to ASIN override.
• [x] The initial scan for J.K. Rowling failed because of timeouts. This might be an API specific issue that needs to be looked into, or add a timeout somehow to fetch requests.

Needs some more QC testing but seemed functional to me
