Sortition Hash is not compliant with specification

[fed-franz]

Description createSortitionHash returns $H(round||iteration||step||seed)$, but the specification states it should be $H(seed||round||step||iteration)$.

Logically speaking, the concatenation order should follow round->step->iteration, like in the specification. Technically speaking, this does not affect correctness/security, as long as all nodes calculate the same hash.

Solutions There are two options:

1. Leave the code unchanged and update the specifications accordingly
2. Adapt the code to the specification
