Add support for reading the current flash contents from a file
When developing software that has to be flashed to a flash chip to be
executed, it often takes a long time to read the current flash contents
(for flashrom to know what pages to erase and reprogram) each time
when writing the new image. However, when the flash was just reprogrammed,
its current state is known to be the previous image that was flashed
(assuming it was verified).
Thus, it makes sense to provide that image as a file for the flash contents
instead of wasting valuable time read the whole flash each time.
