v0.6.7

• cd_variables() gives vpd the unit "hPa", the unit its data has always been in. It said "Pa", so the vpd Unit from cd_anomaly(), cd_trend(), cd_summary() and on the cd_plot_timeseries() axis was off by 100×. Values are unchanged. A table saved under an older cd keeps the "Pa" it carries, because a carried unit wins over the registry, and binding it to new output now errors (two units in one series). Relabel it with x$unit[x$variable == "vpd"] <- "hPa", or recompute from the extracted series. (#96, #134)
