If we say that the version format should be the same for the `version_lowest` and the `version_bootloader` then it does not always make sense to set it at the same time. Moving the `version_format` to a standalone first-class property also means it can be typically be set in the custom device `_init()` function, which means we don't need to worry about *changing* ther version format as set by the USB and UDev superclass helpers.
