Read Pixel modem Pigweed events.

Use a (Perfetto) tokenizer to rewrite events for timestamps like we do for power rails and to load the Pigweed database. Then use a parser to look up events in the database.

The modem implementation specifically then also has a tiny key-value format within the rehydrated event. Use this to label tracks for domains.
