Forcing the original TPC lane configuration for input type digitizer

matthiasrichter · matthiasrichter · commit b07dc8d0cc34 · 2019-04-16T14:20:07.000+02:00
The digitizer workflow is still using the original lane configuration which
distributes data of multiple TPC sectors among subsequent time slices. This
will be changed in the future when the work on staggereing is completed, but
for the moment this needs to be forced in `tpc-reco-workflow`.
