#' @title Check if data is tidy-formatted ws_monitor data

#' @description
#' Verifies that the given data can be treated as tidy-formatted "ws_monitor"
#' data. This is done by verifying that the data is a tibble data.frame object
#' with columns for information in all `ws_monitor` objects.
#'
#' @param data Data to validate.
#'
#' @return True if the data is in a recognized 'Tidy' format, otherwise False.
