Generating cursor value for RSS
On the web-based frontend there is the option to "_Load More_" which uses the `cursor` parameter and a value to allow the next set of tweets to load.

This also works if I append it to the RSS URL:

https://nitter.net/TwitterSupport/rss?cursor=HBaEwL7J9ZC2jSkAAA%3D%3D

However there is no documentation (that I could find) that explains how this hash is generated (or what it is based upon) and I am too new to the Nim language to understand the `getCursor` method.

Alternatively, is there a way to return more than the default 20 results?
