Result set size and paging

[mustberuss]

A user in the patentsview forum asked why their config file produced fewer results when their conditions were removed (*). In looking at the wrapper code, it looks like it is only using the preview of 25 results and not attempting to page through the results set.

I forked your repo and added code to address this though I don't have much experience with python. I have even less experience in making PRs and didn't know whether an issue should be created before submitting a PR out of the blue. What I added will request the api's maximum of 10,000 matches per request and will issue subsequent page requests as necessary.

(*) The user's requests looked to be of different sizes since they asked for cpc_subgroup_id and received multiple rows per patent. When this field was removed both requests generated only 25 rows.

Thanks for point this out! Feel free to make a pull request and we will test it out and approve it (probably not until this next release cycle though).

Best,
