About R1 calibration in EvB for interleaved events

[FrancaCassol]

Hi,

if we want to have interleaved events calibrated in the EvB, I think the easiest way is to move the interleaved event DataWriter in ctapipe_io_lst and to write out the interleave waveforms in this point

We will then remove all processing of interleaved events from the r0_to_dl1 module (both writing of waveforms and calibration).

Also, for the moment I would not gain select the interleaved events in the EvB (in order to write interleaved waveforms with both gains), otherwise this will imply major changes in the lstcam_calib code. We can keep as target to do it in future.
