Fields not properly filled with "old structure" option

Apparently some fields in Trun trees like first_event, first_event_time, last_event, last_event_time are not correctly set when using -os option (as well as in previous gtot versions). It seems correct when using the new structure (with different root files inside a directory).

Ex: With new gtot version (branch GP13_CD_update - Nov 4, 2024 - 512e25c0): gtot -g1 -os -i GP13_20241001_013854_RUN127_UD_RAW_ChanXYZ_20dB_12DUs_312.bin first_event: 4294967295 first_event_time : 0 (Thursday 1 January 1970 00:00:00) last_event : 0 last_event_time : 0 (Thursday 1 January 1970 00:00:00)

gtot -g1 -i GP13_20241001_013854_RUN127_UD_RAW_ChanXYZ_20dB_12DUs_312.bin first_event: 0 first_event_time : 1727746733 (Tuesday 1 October 2024 01:38:53) last_event : 8027 last_event_time : 1727746849 (Tuesday 1 October 2024 01:40:49)

with old version (branch fv2 - Jun 26, 2024 - 25634ab2) : gtot -g1 -i GP13_20241001_013854_RUN127_UD_RAW_ChanXYZ_20dB_12DUs_312.bin first_event: 1727746850 first_event_time : 61 (Thursday 1 January 1970 00:01:01) last_event : 858869831 last_event_time : 842019423 (Friday 6 September 1996 14:17:03)
