Merged requested to merge jcatmore/athena:22.0_IDTIDE_updates into 22.0
This MR applies further adjustments to the IDTIDE format, namely:
- puts a basic pre-selection sequence in place (not as sophisticated yet as the sequencing in the legacy version)
- adding EventInfo to the names-and-types dictionary - explanation for this is in the JIRA above
Note to shifters that there remains a lot of commented out python in the modified file, but this is kept in place since there is some uncertainty about whether it may be needed.
