BOZ analysis rounding issuer in time delay

We have a rounding issue in the small data notebook where delay in mm is recalculated from delay in ps but not with the same constant: 2/c_*0.15*354.90 = 355.1456921574724

This also affect the extra-metro boz online analysis @carinanc

Also, we just realized that a bin width of 0 in the online analysis put the processing in error. That should be prevented without losing the accumulated data by resetting/re-configuring the device @carinanc

one could use the tb.positionToDelay and tb.delayToPosition functions.
