Update tracking_parameters.py

beta_values reader function added, altough it still needs to be fixed as it uses the data thas is downloaded by castor, so it should be integreted with the castor_script block

the seeds, angles and amps are now calculated by 3 independent functions, to enhance readability of the code

param function deprecated: it is not clear why i should need the rat and sigma values, and why sigma values are different from angle to angle
