Atomic class shoud be reorganized.

I noticed in moldb.py, now there are only atomic databases. We should reorganize Adb classes.

Hello,
We have a GSOC working on atomic spectra on the radis side. If you have quick comments to pass before the project is finished, do not hesitate!

• Kurucz database - Adding support for the Kurucz atomic database radis/radis#652
• NIST database - Adding support for the NIST atomic database radis/radis#689

EDIT: sorry for the spam, I thought at first your post was linked to RADIS GSOC but it is not!

Hello,
Great! Are these implementations included as a common API?　
radis/radis#558
If so, ExoJAX will use these capabilities instead of the internal I/O.

Indeed, the objectives of the GSOC were to implement 2 atomic databases in a new common API. The new databases took more time than expected. Thus, for the moment, NIST and Kurucz will be downloaded as we do for HITRAN, ExoMol, and GEISA... but we are still planing on doing the common API!!!
