Chaosthebot#437: Upgrade requirements

Description:
The previous version of `cryptography` failed to build on my system because I had openssl 1.1. The new version fixes that. I also upgraded `requests` for good measure.

Reminder for meritocracy review :)

:ok_woman: PR passed with a vote of 13 for and 0 against, a weighted total of 12.5 and a threshold of 6.6, and a current meritocracy review.
