/** 
 * Initialize the CSPRNG used by the nonce with the seed value provided so that it is deterministic in generating random data. Again, because the CSPRNG is deterministic if you have already used the  CSPRNG and initialized the Nonce object with the same seed value to  generate nonces previously, you must create this object using the last  nonce state in order to prevent reusing nonces/IVs, which is a security  vulnerability. Lastly, if you initialize this object with incorrect seed value needed to generate the last nonce state the CSPRNG will eventually exhaust generating random numbers when it reaches MAXCYCLES and throw an exception, this prevents having to deal with the halting problem, where the program will run indefinitely generating random data.
 * @param seed The seed value for the CSPRNG, must be specified
 * @throws MaxBytesExceededException If CSPRNG reaches MAXCYCLES trying toreturn to the initial Nonce state, usually when the seed data provided is different than the previous seed data used to generate the last nonce state
