Added series name and URI scraping

[sgloutnikov]

Added series scraping if a book is part of a series. If it is not, an empty string is used ("" for JSON and ,, for CSV).

Ex: https://www.goodreads.com/book/show/2657.To_Kill_a_Mockingbird

• Series Name: To Kill a Mockingbird
• URI: /series/255474-to-kill-a-mockingbird

I was getting an error importing HTTPError from urllib.request in Python 3. urllib.error package holds that exception.
