Incorrect Links in the readme and documentation #22

I am trying to understand how to specify the page size of the output pdf when I am trying to convert a source excel to PDF.
I came looking for the docs, and found a section called "Additional conversion parameters" in the official documentation as well as the README.
The first paragraph of the section promises that "All conversion parameters and explanations can be found here."

If we go to that page, we expect to find a list of all conversion parameters and explanations. Instead, we reach the home page of convertAPI where these details are not available.

How to find that list? Once found, I will send a PR with the link modified.
