Normalize input EMG F #28

Hope is that this will fix APFL from blowing up, as norm FF.T is like 40M. Check to see what L is after fixing this.

We normalize the matrix input (batch from update) not the channels individually, since I think scale matters for PCA (eg relative scale between channels needs to be preserved).

Normalize F before doing PCA

Did this and it didn't solve the problem, but it messed up the other trials pretty badly...
