Holy new code!
Great stuff. My main additional request is to add a few
tests related to the new width code.

I think it makes sense to me after a lot of staring

This update is to begin modelling CRACO.
I have added code from Andy to calculate CRACO beamshapes.
However, the ability of CRACO to probe wider FRBs - and evidence from observations - suggests the need to update scattering. We now have the ability to set intrinsic width ~ (1+z) and scattering to go as (1+z)^-3
See new plot in scripts/Scattering that shows the effect of different scattering treatments,.
I have NOT updated the default values however. Nor have I determined if the new upper-lognormal (lognormal on lower-side, log-constant on upper side) function is reasonable. Next step is to work out how to fit for this!
