Atmosphere data absence

[xinshunzhangTHU]

When I used mceq version 1.2, I found the atmosphere data files like "libcorsikaatm" and "libnrlmsis" not available. I wonder if I make use of mceq incorrectly or these files need to be downloaded from other source.

@xinshunzhangTHU these should be avail with the package install. Can you try the new version 1.3.0? 😊
