#' Read ExpertGuess
#'
#' Read-in data that are based on expert guess
#'
#' @md
#' @param subtype Type of data that should be read. One of
#' - `Chinese_Steel_Production`: "Smooth" production estimates by Robert
#' Pietzcker (2022).
#' - `industry_max_secondary_steel_share`: Maximum share of secondary steel
#' production in total steel production and years between which a linear
#' convergence from historic to target shares is to be applied.
#' - `cement_production_convergence_parameters`: convergence year and level
#' (relative to global average) to which per-capita cement demand converges
#' - Any of the others nobody cared to document.
#' @return magpie object of the data
