Implementations of Various Slice Samplers

Implementations of the quantile slice sampler of Heiner et al. (2026+, in preparation) as well as other popular slice samplers are provided. Helper functions for specifying pseudo-target distributions are included, both for diagnostics and for tuning the quantile slice sampler. Other implemented methods include the generalized elliptical slice sampler of Nishihara et al. (2014) < https://jmlr.org/papers/v15/nishihara14a.html>, latent slice sampler of Li and Walker (2023) , and stepping-out slice sampler of Neal (2003) , as well as independence Metropolis-Hastings and random-walk Metropolis samplers.
