This allows us to 'nest' firmware formats, and removes a ton of duplication. The aim here is to deprecate FuFirmwareImage -- it's almost always acting as a 'child' FuFirmware instance, and even copies most of the vfuncs to allow custom types. If I'm struggling to work out what should be a FuFirmware and what should be a FuFirmwareImage then a plugin author has no hope. For simple payloads we were adding bytes into an image and then the image into a firmware. This gets really messy when most plugins are treating the FuFirmware *as* the binary firmware file. The GBytes saved in the FuFirmware would be considered the payload with the aim of not using FuFirmwareImage in the single-image case.
