Jakob Unterwurzacher 32102447e0 reverse: Filesystem is read-only of uniqueIV is enabled
Writing to the ciphertext files can rewrite the header. This
would mean we had to re-encrypt the whole file with the new IV.

This could be made more fine-grained, for example allowing
writes to everywhere but the header. However, this is
something that needs a lot of testing to ensure correctness.
Writing to the ciphertext is a niche use case of the niche
use case of using reverse mode, so it is unlikely it would
get the test coverage it needs.

To be safe, we deny all modifications of the ciphertext with
read-only filesystem error (EROFS) if uniqueIV is enabled.

Reverse mode with uniqueIV disabled still supports writing,
if somebody really needs it. This use case is not covered
by the test suite at the moment.
