gm_report to add one file at startup.
When gm_report starts up it should build a file report_gm_baseline.json -- this is created once after the first largest interval passes and then not created again. This file contains ALL SCNL detected even if threshold is not exceeded. Otherwise the format is the same as report_gm.json. Every smallest interval will output report_gm.json as usual, with only the threshold crossing stations. This allows the front end to know about all currently active stations.
