`[fcs powers] = ewert2000(data,fig,fs)` computes the
EPSM-filterbank as presented by Ewert & Dau 2000, without the additional
lowpass filter with a cut-off at 150 Hz. This implementation consists of
a lowpass filter with a cutoff at 1 Hz, in parallel with 6 bandpass
filters with octave spacing. the Center-frequencies of the bandpass
filters are lower than the original from Ewert & Dau (2000). In each of
the filters data is integrated within the pass-band of the filter to
give the power within that filter.
