ChannelSelector num_channels parameter

[namsaraeva]

This parameter is redundant. Should be replaced with something better or we should get rid of it

[sophiamaedler]

How about we get rid of it and replace it with an assertion that the selected channels are smaller than the maximum number of available channels.

Not sure how best to include it though because the transformers are defined before they are applied to the data.

@sophiamaedler yes, i was also thinking about assertion in the method, but as you mentioned, transforms are defined before they have seen the data. maybe we should just put something in the Dataset class where transforms are applied.
