Description

Reimplementation of published O2 absorption line cross-section algorithm

Based on:
	Dmitriy S. Makarov, Mikhail Yu. Tretyakov, Philip W. Rosenkranz, JQSRT 243, 2020,
	Revision of the 60-GHz atmospheric oxygen absorption band models for practical use,
	https://doi.org/10.1016/j.jqsrt.2019.106798

Note that this is only really applicable to Earth and at lower altitudes.
The only two tested derivatives are for frequency and for temperature but
other untested derivatives are available for all model parameters except a2
