Add trimmed jet triggers
Implemented a basic groomed jet configuration in JetRecConfig, as the foundation for setting up trimmed jet triggers in LS2_v1. Added 2 chains from Run 2, and expanded the SignatureDict entries so that they are understood. Made JetRecConfig.py executable as test.
@peter, this required me to fix a seeming bug in ChainLabelParser -- SMC conditions were not being properly formatted.
Local tests were affected by ATR-19929, but I think this may not show up in the CI as it's jet test specific.
