calculate_13CO2

This function calculates mole fractions of 13CO2 based on the total CO2 mole
fraction, the delta13C value of the mixture, and the assumed fraction of CO2
that does not correspond to 12CO2 or 13CO2 (assumed fixed at 0.00474, e.g.,
Griffis et al. 2004 Agricultural and Frest Meteorology)

Functions for downloading,
calibrating, and analyzing atmospheric isotope data bundled
into the eddy covariance data products of the National Ecological
Observatory Network (NEON) <https://www.neonscience.org>.
Calibration tools are provided for carbon and water isotope products.
Carbon isotope calibration details are found in Fiorella et al. (2021)
<doi:10.1029/2020JG005862>, and the readme
file at <https://github.com/lanl/NEONiso>. Tools for calibrating water
isotope products have been added as of 0.6.0, but have known deficiencies
and should be considered experimental and unsupported.
