Description
Right now, ocb3 exclusively uses BlockCipherEncrypt::encrypt_block and BlockCipherDecrypt::decrypt_block. Although VAES support is coming in block-ciphers#491, ocb3 won't be able to take advantage of its (2-5x) speedups until encrypt_blocks*/decrypt_blocks* APIs are used.

Research direction
Start by locating ocb3's uses of BlockCipherEncrypt::encrypt_block and BlockCipherDecrypt::decrypt_block, then read the parallel encrypt_blocks*/decrypt_blocks* APIs introduced for block-ciphers#491. The work is done when ocb3 uses the parallel-capable APIs where applicable and its existing behavior remains correct.
