Added
- Support for the new alternative calibration files for the `egait_parameter_validation_2013` dataset.
Basically, we found out that the original calibration files were not that good and added new ones to the public
dataset, that should result in significantly better results when calculating spatial gait parameters.
- All datasets now have images visualizing the applied coordinate system transformations.
- The stair pyshoe dataset has now a new index column describing the number of levels the participant walked during a
single trail.
