#' Convert the CV to the log10 sd (log-normal variable).
#'
#' \code{cv2logsd} converts the CV from a log-normal variable to the log10-transformed standard deviation.
#'
#' This function converts the CV to the log10-transformed standard deviation, by taking the square root of \code{cv2logvar}.
#'
#' @param x A numeric value, vector or list.
#'
#' @return Returns log-transformed sd
