Issue/#909 Dependency updates (#910)

* Bump pyjwt

* Skip uvloop install on windows

* Disable uvloop in dev config

* Pin hypothesis to avoid prerelease dependency

Pipenv currently will not install prerelease subdependencies unless you 
enable prerelease dependencies globally. However, we don't want to be 
using prerelease dependencies of other packages and we don't want to 
resort to pinning every other package.

* Run `pipenv lock`
