Add Transitive Dependencies to `setup.cfg`

[Colt Allen]

btyd installs & runs without a hitch whenever creating a new Python environment, but when installing in managed environments like DataBricks or Google Colab, previously installed dependencies like scipy and numpy are not automatically updating and can make btyd unusable.

For now this is easily remedied by updating scipy and numpy to their latest versions, but for version 0.1b2 I intend to add an [install-requires] line to setup.cfg and fix this.
