Time-of-flight: do we still need to rename to tof?

[nvaytet]

ess/spectroscopy/indirect/time_of_flight.py:84: in monitor_time_of_flight_data
monitor_data=monitor_data.rename(t='tof'),

Is this still needed? We need to check that the downstream code can work without the rename?
The dimension could either be t or event_time_zero in newer files.
