version 1.3.0, 2021-03-05
- calc_E(): new function: Calculate E temperature coefficient.
- calc_alpha(): includes an added parameter (avg_top_n) to calculate alpha based on the average of a defined number of observations rather than just the single highest value.

- calc_b(): can now handle 0 values in either the mass or MO2 parameters when using the "lm" mode.
