Amplifier resolution in brainampsocket

[felixilgatto]

Hey
I notice that the BrainAmpSocket node, doesn't take into account the resolution of the amplifier.
So I suggest this small fix in the thread of this node.

# brainampsocket.py

# Extract numerical data
block, points, nb_marker = struct.unpack('<LLL', rawdata[:hs])
sigsize = dt.itemsize * points * self.nb_channel
sigs = np.frombuffer(rawdata[hs:hs+sigsize], dtype=dt)
sigs = sigs.reshape(points, self.nb_channel)
head += points
sigs = sigs * self.resolutions[np.newaxis,:] # here
self.outputs['signals'].send(sigs, index=head)

I also pass in thread argument the resolution array.

# brainampsocket.py

class BrainAmpThread(QtCore.QThread):
    def __init__(self, outputs, brainamp_host, brainamp_port, nb_channel, resolutions, parent=None):
        QtCore.QThread.__init__(self)
        self.outputs = outputs
        self.brainamp_host= brainamp_host
        self.brainamp_port= brainamp_port
        self.nb_channel = nb_channel
        self.resolutions = resolutions # here

        self.lock = Mutex()
        self.running = False

Hi.
thanks for this.
Would you be OK to make a PR ?
