Add event timestamps to the trigger_statistics.py output in the DQM (#308)

* 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
