Add support for sending remaining options with query

[danielwestendorf]

• Append all non-standard options to the query url
• Rely on Faraday's query string encoding

Some endpoints (like invoice) require additional parameters on the query URL to get additional attributes (like include=invoiceLink).

:+1: Tested in our app and this PR is working great.

invoice = invoice_service.find_by( doc_number: dn, include: "invoiceLink" )
