BUG: Import raw CNT file channels in integer format; not strings

Having trouble importing raw .CNT file. Previous steps include importing os, importing MNE, importing numpy as np, importing mayavi, setting log level, importing cnt, defining the file path, and defining the raw_fname. When trying to use read function I get the following:

`In [12]: raw = mne.io.read_raw_cnt(input_fname='./raw/s1066.cnt', montage=('montage'), eog=('VEOU', 'VEOL', 'HEOR', 'HEOL'),

I’d be glad to share the files we’ve been trying to import. Having the real files will be invaluable for this kind of debugging. I’ve got three sample files, all of which have been successfully imported using a custom Matlab toolbox and which are readable in Scan from the vendor’s software.

How would you like us to send them to you?

Glad it works !
