It's actually quite hard to build a front-end for fwupd at the moment as you're never sure when the progress bar is going to zip back to 0% and start all over again. Some plugins go 0..100% for write, others go 0..100% for erase, then again for write, then *again* for verify. By creating a helper object we can easily split up the progress of the specific task, e.g. write_firmware(). We can encode at the plugin level "the erase takes 50% of the time, the write takes 40% and the read takes 10%". This means we can have a progressbar which goes up just once at a consistent speed.
