//! CFTC Commitments of Traders provider implementation (keyless).
//!
//! CFTC publishes no price quotes, so `fetch_futures_quote` — `FuturesProvider`'s
//! required primary operation — reports `NotSupported` and dispatch falls
//! through to a quoting provider (e.g. Polygon); `fetch_commitments_of_traders`
//! is the operation this provider actually serves.
