introduce calibration dictionary

[steinnymir]

A great improvement would be to define a dictionary with all calibration and correction parameters which should be passed to the different calibration methods. This would allow easier transfer between different datasets of calibration/correction parameters, as well as making it possible to store them together with the data, to increase the re-usability and transparency of data treatment.

The idea would be to have, at the final stage, a single method to call: processor.calibrate(calibDict) which will run all the calibrations/corrections which have an entry in the dictionary.

If I remember correctly, MPES has something similar. Some feedback from the MPES guys about this idea would be great! 😄 @RealPolitiX.
We might even try to make the two compatible with eachother, if this is even possible.
