Extend triggers information when possible

[eagoetz]

This PR adds functionality to get_triggers so that when parameters like tstart and tend are requested to be extracted from omicron trigger files (but not duration), the duration column will be computed and added to the trigger table. This also works when fstart and fend are requested (but not bandwidth or central_freq), then bandwidth and/or central_freq will be computed and added to the table.

Together with updated configuration files, https://git.ligo.org/detchar/ligo-summary-pages/-/merge_requests/395, we can see the updated version of the glitches page here: https://ldas-jobs.ligo-wa.caltech.edu/~evan.goetz/summary/day/20240101/lock/glitches/

Compare to the original page: https://ldas-jobs.ligo-wa.caltech.edu/~detchar/summary/day/20240101/lock/glitches/

The only difference is that "Peak frequency" is renamed to "Frequency" in some labels
