#' into a data frame of subtitle groups.
#' @param path A path or connection to an `.srt` file.
#' @param collapse The character with which to separate subtitle lines.
#' @examples
#' # read linear text to tabular data
#' read_srt(srt_example(), collapse = " ")
#' @return A data frame of subtitles.
