Also, the sign check was moved to the end of lead_field_matrix from
lead_field_eeg_fem, because the source interpolation after at the end of
lead_field_matrix caused yet another sign flip.

Updated function zef_lead_field_sign to calculate the signs of the lead
field in x-, y- and z-directions separately.
The function lead_field_eeg_fem multiplies the columns of L_eeg
corresponding to these directions to ensure correct L_eeg orientation.
Moved EEG lead field sign flip(s) to the end of lead_field_matrix from lead_field_eeg_fem
zef_lead_field_sign: ensure the test electrodes are in the direction the test source dipoles point to
