[Mne_analysis] Spectral analysis with LCMV

[Eric Larson]

        External Email - Use Caution        

You should be able to compute the LCMV source values using
apply_lcmv_epochs, then loop over the resulting STCs, passing stc.data to
psd_multitaper:

If you want it to be more efficient, you could write more complicated code
to compute the single-epoch spectral estimates (linearly, not computing
power or absolute value), apply the LCMV filters to these, then take the
power (or abs). But it would involve more complicated code.
