Panic When Opening or Sealing on Export-Only Context

Constructing an HPKE Context with the AEAD algorithm set to HpkeExport resulted in a panic when calling Context::seal, or Context::open. This was due to an underflowing integer subtraction when calculating the length of a vector allocation for the AEAD nonce, which would panic on its own in debug...
