Subject: Get rid of code duplication for conj_helper. For packets where
 LhsType=RhsType a single generic implementation suffices. For scalars, the
 generic implementation of pconj automatically forwards to numext::conj, so
 much of the existing specialization can be avoided. For mixed types we still
 need specializations.
