fit_noise() gains a censor parameter
for motion scrubbing support. Censored timepoints (e.g., frames with
high framewise displacement) are excluded from
AR parameter estimation. Accepts either integer indices or a logical vector. The time series is segmented at censor points and ACVF is pooled across valid segments with proper length-weighting.
whiten() now passes censor to both
fit_noise() and whiten_apply().
The returned fmriAR_plan object now includes the
censor indices for downstream reference.
