use get_data instead of ._data

PR Description

fixes #127

Not really sure what the problem was over there, but the adjustments here are minor (get_data() should yield the same as ._data, except that it takes a tiny bit longer) and it'd fix the issue.

@Sam54000 when you install pyprep from this branch ("data", https://github.com/sappelhoff/pyprep/tree/data), does this fix your problem?

[Sam54000]

I installed pyprep from the branch "data" it works.
Also you right it is something to do with the preload: the mne-bids function to read raw doesn't have explicitely the preolad option so I assumed it was taking care of (I tried with the main branch). Then I figured that I have to specificaly pass the option through extra_params like this: mne_bids.read_raw_bids(bids_path=bids_path, verbose=False,extra_params={'preload' : True}). So yes if it is faster with ._data we should keep this as it is. Maybe changing the code to throw an error saying that raw needs to be preloaded if ._data doesn't exist?
Thank you very much for your help and sorry for this

Thanks for testing and the additional info! I think I will merge this fix, because the impact on performance is really negligible (the newly introduced get_data will not (!) be called hundreds of times in a loop). if you want to prepare a PR that introduces a check for preload, please be my guest!
