Remove MD5 from ObjectId generation

      In FIPS environments hashlib.md5 isn't available or just fails. We don't technically need it for ObjectId generation.

      We've decided to replace md5 with FNV-1a, 32 bit xor-folded to 24 bit. A few other drivers already use non-cryptographic hashes for this (e.g. Java and .NET), a cryptographic hash is not required, and using a non-cryptographic hash avoids ever having to deal with this again in the future.
