Calculate smoothed ALFF from smoothed BOLD

[tsalo]

Closes #1132. Reproduces #1124.

Changes proposed in this pull request

• Pass smoothed, denoised BOLD into init_alff_wf and use that to calculate the smoothed ALFF instead of smoothing the ALFF image calculated from the unsmoothed BOLD data.
• Pass the censored, denoised BOLD into init_alff_wf instead of using the interpolated data and censoring it within the workflow.
