Add dependency checker

[Andrew Montanez]

Problem Description

As a developer, I'd like to know if a new version of a library we depend on is incompatible or not so that we can make changes to support it.

We want to add an automated dependency checker that will install the latest versions of each dependency, run the tests against our library and then update the latest supported dependencies in a file. The bot can open a pull request to do this.

Expected behavior

• Add a workflow that
  1. Installs Copulas with the latest version of every dependency
  2. If any of the dependencies have a new version, update a file to track this
  3. Make a Pull Request to update the dependency list

To support this, the following changes need to be made:

1. We have to uncap our dependencies
