Algorithm 2: Chaining Function.
Takes an n-byte input string and transforms it into a the function result iterating the cryptographic hash function "F" steps times on the input x using the outputs of the PRNG "G".
This overload is used in multithreaded scenarios, where it is required to provide seperate instances of XMSS_Hash to each thread.

Return the estimated strength of the underlying key against the best currently known attack. Note that this ignores anything but pure attacks against the key itself and do not take into account padding schemes, usage mistakes, etc which might reduce the strength. However it does suffice to provide an upper bound.
