fix experiment hash by not hashing _measurement schedule_

related to

• #9

in order for the measurements not to influence the experiment, the seeds passed to the runs need to not include the measurement schedule parameters!

EDIT: in the end, it's more than that, we want to only include things related to the environment in its hash, nothing related to the measurements, i.e. we want to either

• exclude strategies, nb_scenarii, measurement_schedule, measurement_schedule_start, nb_measurements and max_t
• include nb_bytes, k, n and environment
