UK Open Data inputs

**UK Open Data** is a UCC-framework built add-on that brings two well-known open UK datasets into Splunk with no API key and no external dependencies beyond outbound HTTPS. **Carbon Intensity** — polls the National Grid ESO Carbon Intensity API (`api.carbonintensity.org.uk`) and indexes, per half-hourly settlement period, the national forecast/actual gCO₂/kWh and intensity band (`carbonintensity:national`) plus the generation mix by fuel type (`carbonintensity:generation`). Ideal for carbon-aware scheduling, ESG dashboards and "greenest time to run" decisions. **NHS A&E (monthly)** — scans the NHS England "A&E Attendances and Emergency Admissions" pages, downloads each monthly CSV you haven't already loaded, and indexes one event per provider plus a national TOTAL row (`nhs:ae:monthly`) — type 1/2/other attendances, 4-hour performance and over-4hr counts. Great for healthcare performance and public-sector analytics. Both inputs are **idempotent**: they checkpoint what they've already indexed, so they're safe to run on any interval without creating duplicates. Carbon re-emits only un-settled recent periods until their actual value lands; NHS only loads months it hasn't seen. Built with the Splunk UCC framework — full configuration UI, per-input index/interval settings, and standard logging.
