  Descriptions API.

  Static, mostly language-dependent metadata that describes the values used
  throughout the feed: market and variant descriptions, producers, sport-specific
  match statuses and betting statuses used in `odds_change` messages, betstop
  reasons, and void reasons used in `bet_settlement` messages.

  Every function returns `{:ok, struct} | {:error, Ecto.Changeset.t()}`, where
  the struct is an `UOF.Schemas.API.Descriptions.*` embedded schema. Endpoints
  that vary by language take an optional `lang` (ISO code, default `"en"`).
