Integrate FW configurator

[julianneswinoga]

Currently you need to generate configuration with https://config.openastrotech.com/, then import it into OATFWGUI. Ideally this would all be handled in the GUI.
We'd still want the ability to import a custom header configuration (for advanced users) but the majority of users would just need to click through some options.
As a part of this we would need to standardize a parsable configuration file so that users wouldn't need to re-input all their options every time they re-launched the GUI.
