Bump version numbers of outdated dependencies

Use https://requires.io/github/nowyasimi/no8am/requirements/?branch=master to update dependencies in requirements.txt and add a requirements badge to the README.

Are you sure updating the dependencies would result in a clean build? It makes sense to update requests to a secure version, but I am not sure about the others.

Updating requests is definitely the highest priority. We'll have to review the other dependencies on a case-by-case basis, but I don't anticipate any breaking changes based on the changelogs I've looked at so far. Ideally, we would have more python tests to help speed up the process!

Furthermore, in the future, we could enable Doppins on the repository to automatically submit pull requests with updated versions of dependencies.
