Can no longer pass keyword arguments to dynesty

[radicamc]

As the title says, keyword arguments are no longer able to be passed to dynesty via juliet.fit (not sure about other samplers).
I believe this is because line 1683 args = vars(sampler).keys() is not actually returning a list of possible dynesty arguments, resulting in everything failing the cross-check with the passed keywords.

Fixed on latest version (2.2.6).
