Add hydrologic Year, month, and doy columns to a daily time series

Screens daily streamflow time series for temporal trends and
change-points. This package has been primarily developed for assessing the
quality of daily streamflow time series. It also contains tools for plotting
and calculating many different streamflow metrics. The package can be used to
produce summary screening plots showing change-points and significant temporal
trends for high flow, low flow, and/or baseflow statistics, or it can be used
to perform more detailed hydrological time series analyses. The package was
designed for screening daily streamflow time series from Water Survey Canada
and the United States Geological Survey but will also work with streamflow time
series from many other agencies.
Package update to version 2.0 made updates to read.flows function to allow
loading of GRDC and ROBIN streamflow record formats.
This package uses the `changepoint` package for change point detection.
For more information on change point methods, see the changepoint
package at <https://cran.r-project.org/package=changepoint>.
