Nested sampling integration

[mvsoom]

Very happy to hear about the funding from Alan Turing Institute!

I was wondering if there is still interest for working on the NestedSamplers integration, as this is possibly a very powerful sampling backend (for example popular in the astronomy community). Previous attempts seem to have stranded.

Very willing to help out by testing and contributing to the nested sampling code itself, but the integration into Turing is well over my head.
