Package Updates

[teddyrendahl]

Description

There were some API breaks in the newer release of typhon, in response we had pinned the version in the conda-recipe here. This updates all typhon calls in the library to use the new API. There were also a few other odds ands ends from updates in other libraries.

• No longer need a PyDMApplication and no longer need to call establish_widget_connections after creating widgets
• flake8 now has a few more rules that I was in violation of.
• Also after dealing with a ton of widget related segfaults, wanted to make sure we were setup for success and using pytest-qt to test the GUI components.
