25577e0eaf Assert active and dfu have same erase size and copy in smaller chunks 
The copy from active to dfu (and vice versa) is now done in smaller portions depending on aligned_buf, which now does not need to be erase_size big.

df3a1e1b9d Avoid write to not-erased magic 
This introduces an additional marker to the state partition right after the magic which indicates whether the current progress is valid or not. Validation in tests that we never write without an erase is added.

There is currently a FIXME in the FirmwareUpdater. Let me know if we should take the erase value as a parameter. I opened a feature request in embedded-storage to get this value in the trait. Before this, the assumption about ERASE_VALUE=0xFF was the same.
