DQM add timestamps and event ids to trigget statistics output (#313)

* feat(src/nectarchain/dqm):

- trigger_statistics.py: add arrays of event timestamps to get_results(), to be written into the database

* refactor(src/nectarchain/dqm):

- trigger_statistics.py: convert event timestamps in output directly to arrays

* feat(src/nectarchain/dqm):

- trigger_statistics.py: add arrays of event ids to get_results(), to be written into the database

* refactor(src/nectarchain/dqm):

- trigger_statistics.py: refactor get_results to not include empty arrays, and remove event_wrong_id

* add event_wrong_times in TRIGGER-EVENT-TIMESTAMPS if array is non-empty

* fix results dictionaries in trigger_statistics
