Memory is on. The blob is in flash, and the first bit of the blob is the
header with the length field.
We do a memcpy from flash to the struct, but first we have to cast it to a
header so we can read out the length to copy. Gcc doesn't like the cast, so
we just declare that we have the header stored in flash.
One way to solve it would be to copy the header first, then read the length
and copy the rest...
It doesn't seem like there are any clean ways to do it. The way it's done
now depends on the unsigned character array being 4-byte aligned.
