Added ability to force polarization to be entirely eTheta or ePhi in efield reconstruction using VoltageToEfieldConverter. Was added so that we can use voltageToEfieldConverter on all the dipoles only and get a reasonable reconstructed electric field. It was necessary because the cross-pol component of the dipoles is extremely small, which caused the ePhi component to be artificially enlarged by many orders of magnitude larger than the eTheta component.
