//You might wonder: Collin, what in the hell is this for? Firmware uploader? For what? I'm interested! Well, it's a custom
//firmware uploader for a motor controller I built. Why would that be in this project. Cuz. It's not really relevant
//to anyone else but might serve as a decent reference for a few things: How to make an uploader interface that runs over CAN,
//how to lay out a screen like this, how to make a comm protocol for firmware updating over CAN. But, most things use UDS
//for firmware updates and wouldn't need this specific code. But, it might be able to be turned into a UDS firmware uploader or downloader.
//Note that this screen is specifically hidden by default because of it's oddball status. You have to re-enable it in mainwindow.cpp to see it.
