UltraNest support

[JohannesBuchner]

Would you be interested to add support for https://johannesbuchner.github.io/UltraNest/ ? The interface should be very similar to dynesty. UltraNest is a very reliable tuning-parameter-free algorithm. It can be faster than dynesty, especially if you take advantage of vectorization. It also supports resuming from disk and MPI parallelisation, if that is useful to you.

Very Cool! I was not aware of UltraNest, thanks a lot! including another sampler to the Exostriker should be easy in the core, but a bit time-consuming on the GUI part. Yet, I will definitely have a look and experiment! Comments are likely to follow, so stay tuned.
