bcgwcat 0.6.1

• Correct general calculations of water types
  • Allow water types to use Meas Alk if HCO3 is missing (identified by HCO3* in the returned water type).
  • Water type also returns a check column mission_ion to identify if the water type is missing all anions or all cations.
• New function for calculating dominant water types (dominant_water_type())
  in a series of samples.
• Tweak piper plots and stiff plots
  • Use Meas Alk (Total Alkalinity) instead of HCO3 if missing.
  • Omit outlier points (when >5 samples, those not in a Dominant Water Type)
