Extend events() method to accept page and limit parameters

[chrisinmtown]

Extend the PyMISP events() function to accept and send limit & page path parameters to match the behavior of the MISP web UI, which accepts URLs like this and adjusts the page accordingly:

https://misp.my-company.com/events/index/page:1/limit:5

Just guessing, I would implement it like this:
