#' @description Read `.loom`-formatted hdf5 file.

#' @details This reads the whole file into memory. Beware that you have to explicitly state when you want to read the file as
#' sparse data.
#'
#' @param filename The filename.
#' @param sparse Whether to read the data matrix as sparse.
#' @param cleanup Whether to collapse all obs/var fields that only store one unique value into `.uns['loom-.']`.
#' @param X_name Loompy key with which the data matrix `AnnData.X` is initialized.
#' @param obs_names Loompy key where the observation/cell names are stored.
#' @param obsm_names Loompy keys which will be constructed into observation matrices
#' @param var_names Loompy key where the variable/gene names are stored.
#' @param varm_names Loompy keys which will be constructed into variable matrices
#' @param dtype Numpy data type.
#' @param ... Arguments to loompy.connect
