instead of just checking all flag qubits to be 0, one can also check if the resulting measurement correspond to the logical 0 state
Print statements are automatically removed by the formatter. Temporarily disable this for debugging purpose.
this utility function returns the whole automorphism subgroup of the symmetric group based on the given generators of the automorphism group
This function as of now goes through all permutations and checks how many faults overlap in the corresponding fault sets for each permutation.

given a list of qubit indices, add a penalty to each corresponding col of the cost matrix such that those CNOTs are applied later
long-term: reconsider if the EliminationCNOTSynthesizer class needs the code instance. There might be situations where it is not necessary and hence should be avoided to require the code at initialization.
this might need bigger rethinking, so far I am handling the fault sets as initially only as numpy arrays should that stay like this or change?
there is no zero fault set anymore. the 0 fault set element is now the single error fault sets which was before the '1' element in the list

only self created files are used here
this should be discussed again, if we want to keep the tests or only test api functions here. further changes: allow for scenario parameter as this help readability and add module docstring.

Description
We are trying to improve the fault-tolerant state preparation circuits by using code symmetries and/ or restructuring of circuits.
