## Message

```
std.crypto.aegis: Absorb ad instead of encrypting it.

`Aegis256XGeneric` behaves differently than `Aegis128XGeneric` in that
it currently encrypts associated data instead of just absorbing it. Even
though the end result is the same, there's no point in encrypting and
copying the ad into a buffer that gets overwritten anyway. This fix
makes `Aegis256XGeneric` behave the same as `Aegis128XGeneric`.
