Colby sand load method in SEDTRN returns NaN in Anaconda python 3.9.7

[PaulDudaRESPEC]

In the Colby sand load method down in SEDTRN, the log10 function returns NaN in this code, when using the Anaconda python 3.9.7. I've verified that it returns a good value in python 3.7, and it even returns a good number when I comment out the ‘njit’ declaration. It’s just the numba compiled version that returns the NaN. To make it even more perplexing, when I add the print statement below (which I did as I was trying to debug), it works just fine in all versions, even with numba.
