Remove gyrations around CRYPTOPP_NO_UNALIGNED_DATA_ACCESS 

CRYPTOPP_NO_UNALIGNED_DATA_ACCESS was required in Crypto++ 5.6 and earlier because unaligned data access was the norm. It caused problems at -O3 and on ARM NEON.
At Crypto++ 6.0 no unaligned data access became a first class citizen. Folks who want to allow it must now define CRYPTOPP_ALLOW_UNALIGNED_DATA_ACCESS
