[FEATURE REQUEST] Please allow uploading of other file types besides .GCODE & .BGCODE

[JAngerCAN]

Adding the ability to upload other file types besides GCODE would be convenient. One example is the .bbf files. This reduces the amount of USB Key swapping, copying, ejecting, etc one has to go through. Another reason why this would be convenient is my new laptop does not have USB-A ports. So often firmware updates mean I have to go to another floor to get an adapter or find my USBA & USBC memory stick.

This is also handy to keep source files nearby, I tend to organize in folders (which shoud be another feature request)
