[SDS-716] Quantum Volume Computation

[QFer]

• Solves issue Calculating Quantum Volumes #145
• user data added more header data for usage in result handling
• metadata from qiskit header needs to be serialized. Because of numpy arrays we use serializer from qilib
• qilib added to setup
• Some small pylint improvements, f-strings and setting encoding for opening files
• Added parameter allow_fsp to run in order to prevent fsp (manually) for experiments
