Modifications to the Audible via API WS

I guess the reason why I thought it might be Lua is because the Lua code linter seemed to work properly for it

By the way, I thought of another really important Tag that we should add ASIN region a.k.a. which region this ASN came from

Isn't this implicitly available via WWWAUDIOFILE?

I guess I’ve come across a lot of things that have been tagged before things got more standardized and they have ASIN numbers but nothing in the URL

Yes, you'd probably need to update those if you want this information in the file.
