eazy has a nice (MIT-licensed) implementation of the Inoue et al. 2014 (https://arxiv.org/pdf/1402.0677.pdf) mean intergalactic attenuation-- https://github.com/gbrammer/eazy-py/blob/master/eazy/photoz.py#L2671-L2678

And here's another implementation from Becker+13-- https://github.com/MJTemple/qsogen/blob/main/qsosed.py#L524-L562

Next step is to compare these various implementations and choose one.
