I think the test script should generate its own test files, so the user
can simply run it without having to manually set up a bunch of stuff first.

One important test-case is files that are larger than
CONFIG_SYS_DFU_DATA_BUF_SIZE. Is dat_97M.img above intended to be 97MB?
If so, that's probably covered. Testing large sizes that both are and
are-not multiples of CONFIG_SYS_DFU_DATA_BUF_SIZE would be useful.
