Add FlexMeasures plugins, USEF protocol, and Cariflex simulator

- flexmeasures-entsoe: ENTSO-E data plugin
- flexmeasures-weather: Weather data plugin
- USEF Flex Trading Protocol PDF (2.4MB)
- Cariflex simulator (publishes to Redis)
- Dashboard Grafana updated with correct InfluxDB queries
- All tools extracted in /tools/
