Crash at workflow build time if total readout time cannot be determined

[effigies]

What would you like to see added in fMRIPrep?

We know at build time whether we're going to try to run SDC correction, so we should run sdcflows.utils.epimanip.get_trt() on the BOLD metadata to detect whether we can run it.

Do you have any interest in helping implement the feature?

Yes
