feat: Rename vb-request-v2 -> vb-request-with-auth
...
Turns out that Alice reacts to a request-v2 message in exactly the same
way as to a request-with-auth message. So, no need to distinguish here.

Speed up message decryption by not iterating in the s2k algorithm

The passphrase has as much entropy as the session key, so, there is no
point in making the computation slow by iterating.

feat: Increase secret size to 256 bits of entropy
...
This is for quantumn computers. When trying to break AES, quantumn
computers give a square-root speedup, i.e. the 144 bits of entropy would
take as many queries as breaking 72 bits of entropy on a normal computer. This neglects
e.g. the costs of quantumn circuits and quantumn error correction [1], so,
144 bits entropy would actually have been fine, but in order to be on
the very safe side and so that noone can complain, let's increase it to
256 bits.
