Consider adding other sundials routines?

I really like your API here for cvodes and desire having something similar for the IDA solver for DAEs. I know the package name is pycvodes, but would you consider including a wrapper for IDA?

It would be great to have IDA wrapped as well (and more routines for cvodes too for that matter). It's "just" a matter of finding the time to write those. :-)

I notice you have two separate packages: kinsolve and cvodes. Would you recommend a new package for IDA or to add it to one of these? I need IDA for my course at TU Delft so I may be able to put some resources into writing it but would like to add it to your repos instead of making my own (if that makes sense).

I'm fine with adding it to pycvodes. If we at some point in the future want to release a unified package for wrapping sundials or split the IDA part out to a separate package, then that's comparatively a low effort job.

I think the state of the CI-config has gone stale on this repository, so we will probably want to move that to github actions or something similar.
