''' loads one by one patient from raw data folder and if it is seizure file detects where is seizure, and cuts that out
- picks random nonSeizure file (but that hasn't been used so far) and takes FactorxSeizLen data and puts half before seizure and half after
- output is for each seizure cutout in form of one .csv file where first n columns are channels data and last column is label (0 non seizure, 1 seizure)
