What the missing-dpss error looks like without the toolbox and under Octave, and the three options: cfg.taper = 'hanning', cfg.taper = 'sine' with tapsmofrq, and why the dpss_hack is not recommended (it cannot serve ft_specest_mtmfft, fieldtrip/fieldtrip#2614). Requested by schoffelen on that issue.

Updated the title and improved clarity in the explanation regarding the use of dpss without the Signal Processing Toolbox. Added some links to material elsewhere.
