[ENH] Support AAS LaTeX macros for journal names

[dfm]

Many astronomers submitting to JOSS build their .bib files using ADS, but the BibTeX entries there use custom macros for the journal names, defined here. We don't seem to support those macros, but perhaps we could?

I'm happy to open a pull request adding these macros to the JOSS template if others think that would be ok. If not, sorry for this noise!

Sure thing. I think that's reasonable, especially given our relationship with AAS publishing.
