BIDS restrictions on file names may impact conversions

[VisLab]

@arnodelorme @dungscout96 @effigies

bids-standard/bids-examples#442 added new restrictions to filenames relevant to EEG. Do you foresee a problem. I think the current files generated in the bids-matlab-tools include a task in the electrodes.tsv filenamess (at least the ones that we generated last year do). Can you comment if appropriate.

• rules behind the limited number of electrodes.tsv per session should be made more explicit bids-standard/bids-specification#1481
