Detailed description of the feature request:

Today, some people are not comfortable with the flashing process. They do not always know which release to flash, they do not understand that there are two parts and that these parts have to be at the same version level, they are not comfortable with the necessity to open the printer, etc.

So the goal if this enhancement is to provide as much help as possible. The requirements are more or less the following:

• Standalone, desktop tool. No need to install any external tools (i.e. no need to install Arduino IDE, ...)
• Multi-platform (macOS, Windows, Linux)
• Retrieve and display the list of available releases (version number, flavor such as with BLTouch support, perhaps the changelog)
• Check USB connectivity with the printer, the baudrate, any missing driver, etc. Help solve connectivity problems
• Retrieve the versions (both parts) of the firmware currently installed
• Flash the mainboard part with some progress
• If technically possible: flash the LCD part with some progress. I know there are technical solutions to flash the LCD without requiring the opening of the printer. However, the flashing process with way is very slow so I am not sure if it is actually viable.
