v2.7.25

• Added read_waterdata_ratings to access USGS rating curves with
  new modern endpoint.
• Added read_waterdata_peaks to access USGS peak data with
  new modern endpoint.
• Increase flexibility of chunking by monitoring_location_id by
  including it as an argument in each relevant waterdata OGC function.
• Clean up deprecated code.
• Updated retry strategy to include retry_on_failure = TRUE.
• Added countries, methods, method-categories, method-citations, and
  citations to possible values in read_waterdata_metadata.
• Added field_measurements_series_id argument to read_waterdata_field_measurement
• Removed NWIS tests
• Introduce an error if user inputs a numeric to any of the "time" arguments.
  Because it is impossible to tell if they intended Dates or POSIX, we cannot
  know for sure and therefore could add incorrect filters to the query.
• The "id" column that comes back from read_waterdata_field_meta was changed to
  field_measurements_series_id to match the expectation of read_waterdata_field_measurements
• New argument added to read_waterdata_stats_por: "normal_type" accepts
  "DOY" and "MOY"
• New argument added to read_waterdata_stats_daterange: "interval_type" accepts
  "M" (month), "CY" (calendar year), and "WY" (water year).
