error reading fits file in Clusters.ipynb

[alxogm]

I'm getting the following error, in section Clusters observed by DESI of Clusters.ipynb,

---------------------------------------------------------------------------

Error reading data buffer from file:

ffopen could not interpret primary array header of file: 
./tmp/desihigh_redmapper_dr8_public_v5.10_catalog.fits

I've tried both in Binder and Colab. BTW, if we could use astropy to read the fits file would be better since Colab doesn't have fitsio by default, we could install it, but would be simpler if we use astropy...

@jtmyles any chance you could take a quick look at this?

#89 should contain the fix (thanks @jtmyles), but admittedly is showing errors of 'not json of notebook'. To be investigated further.

Would you please copy the entire error message @michaelJwilson?
