Adapt ReEmu configuration to run without csctfDigis

[bortigno]

ReEmulFromRaw relies on csctfDigid so it won't work for any 2017 data.

@rekovic @thomreis Should we add "2016" sequences in customiseReEmul.py, as was done for "2015" before? 2017 will see some changes w.r.t. 2016, e.g. OMTF and CPPF unpacking, and no csctfDigis in data.

hey @abrinke1 it should be taken care by the eras but at the moment I see that for L1trigger 2016 is the same as 2017

Probably a good idea to update that including your suggestion. What do you think @rekovic ?
