Detailed Description

Quantizes an AZ::u64 into 1, 2, 3, 4, 5, 7, 8, or 9 bytes based on highest bit usage. The format of the serialized value is a sequence of 1's specifying the number of bytes trailing the initial byte, followed by a 0, followed by the bits that make up the actual value. For example, the number 98 decimal (one byte) will be encoded as 0|1100010

In the case of 9 byte encoding, the first byte is 0xFF and indicates 9 byte encoding (without a zero to follow for optimization based on assumption that 64bit is the largest integer supported) where as in 8 byte encoding, the first byte is 0xFE.
