compress sd card images differently

[steviehs]

I know I shouldn't but for reasons :-) I use balenaEtcher... and also for piping directly to dd I would suggest to pack the images different: not the img in a tar.gz but directly gzip, or bzip2 or zip the image: foo.img.gz and foo.img.bz2 work with balenaEtcher, just tested it. Thx!
