wishlist: optionally read gzipped or bzip2ed files

[broukema]

FITS files are often highly compressible. With astropy, it's possible to read a gzipped or bzip2ed file with

import astropy.io.fits as fits;  tt = fits.open('file.fits.bz2')

instead of

tt = fitsio.FITS('data/pixweight-dr10-128-new.fits'

It would be good to make this an option in cosmodesi mpytools, without making it obligatory (astropy is a big package so making it obligatory would unnecessarily force the user to install, identify and trace more packages).

I had a quick browse at the code here and tried a quick hack, but it looks like implementing this would require more than changing just one or two lines.

I feel fitsio should be able to deal with compressed files already?
can you try with the last commit: 6eea626?

Thanks!
