BU-hammerTeam/PyHammer: PyQt Update

This release represents an overhaul of the GUI the user interacts with. It improves on the user interface and design by porting the code to use PyQt instead of TkInter as the backend. Small improvements have also been added to the code/process such as not needing to specify the fits filetype anymore or adding a template match metric to the eyecheck GUI.
