Make run_summary script work with ctar1 data, store format string

[maxnoe]

Counters are not used in case of CTA R1 input, so just don't compute them.

We rely on the event_time_s, event_time_qns and the event_type reported by EVB for this.

I don't know if it's intended but the dragon_reference_counter is still being filled in case of CTA R1 data

I think it is somehow not getting COUNTER_DEFAULTS but actually looking into the files for this time information (?)

The dtype of the dragon reference is uint64, the value filled is uint64.max

Tests passing with fixed ctapipe_io_lst
