Exporting ExperimentData to other datatypes shows path to disk rather than data

[maxkukkola]

When exporting ExperimentData that was written to disk, for example using .to_pandas(), the outputted data frame shows the path to the write location on the disk. Functionality would be improved if the outputted data frame already contained the data instead of the path so that user doesn't need to iterate over values with ExperimentSample.get().

Thank you for your suggestion Max! As of now, this might be problematic because that means that in the outputted pd.DataFrame, individual cells might hold data that cannot be stored in a pandas DataFrame cell, like numpy arrays.
