Move from pick_types to inst.pick

[sappelhoff]

See for example:

pyprep/pyprep/find_noisy_channels.py

Line 57 in 82390ac

self.raw_mne.pick_types(eeg=True)

This raises:

NOTE: pick_types() is a legacy function. New code should use inst.pick(...).

Hello, This is my first PR, but I am confident I will be able to update the code. Can you assign this to me? and I will start working on it immediately.

Hey @Ayush-Devs, sure -- please feel free to open a PR.

The raw.pick() method returns the modified Raw object itself, not a numpy.ndarray like pick_types() used to.

if len(arys) == 1:
result = asanyarray(arys[0])

ValueError: setting an array element with a sequence. The requested array has an inhomogeneous shape after 1 dimensions. The detected shape was (60,) + inhomogeneous part.

not really sure how to work around this issue.

Hey @Ayush-Devs, I am making quite a few changes in the background regarding the pyprep infrastructure right now, so it'd be good to not work on this for a while. I had assumed you closing your PR meant that.
