Switch to MNE-Python @verbose decorator

[adam2392]

 raw = read_raw_bids(fpath, verbose=False)

Example output:

Extracting parameters from /home/adam2392/hdd3/sickkids/sub-E1/ses-extraoperative/ieeg/sub-E1_ses-extraoperative_task-interictalawake_acq-ecog_run-01_ieeg.vhdr...

I'm guessing there are a few places that aren't getting passed the verbose parameter correctly.

We should consider using MNE's @verbose decorator so we can stop worrying about manually managing verbosity once and for all.
