Add skip channels to EDF interface

[h-mayorquin]

Related to #1106

This adds the user to the possibility of skipping non-neural channels on the EDF interface.

Some relevant comments:

• Can't add testing right now. The EDF by neo is blocked when reading the format. That means that it does not work well with the parallel machinery that we have in pytest. I have been meaning to fix this on the neo level or add a hack to our pytest machinery but other priorities come first (see EDF blocks access when io is opened. NeuralEnsemble/python-neo#1557).
• Up for debate on how to expose the available channels so the user can pick for them. Ideally, this should be a static or class method but then because of the blocking problem described in the previous point this will not work in a script (getting the channel names requires opening the file). Maybe this is simpler to fix at the neo level by providing a method to closing the objects but I did not want that to get in the way.
• I will open another PR to improve the friendliness of the error for multiple offsets. (Done here Add more friendly error when writing recording with multiple offsets #1111)

This is necessary to display meaningful names that the user can suppress with the newly added parameter. Otherwise, the channel ids are "1", "2", "3", etc.

This is technically a breaking change because we are changing the way we add the data to the NWBFile but I also consider this an improvement:

@h-mayorquin this looks good! Can you confirm that this is able to read and convert the sample EDF file?

Yes, can't attach the stub here but I will send it on slack.
