#' Prepare Aircraft Final for NASA Ames

#' Takes the _final output of \code{wsdmiscr::process.aircraft2()} and preps it for \code{wsdmiscr::create_nasa_ames_1D()}
#' 
#' @param d_final _final output of \code{wsdmiscr::process.aircraft2()}
#' @param missing_flag what should NAs be replaced with
#' @param col_names what should the columns be renamed too
#' @param date_col which column contains the datetime info
#' @param date_parse function to transform the current date into a POSIXct
#' @param origin does date_parse require an origin? include it here
