Function to execute single MCMC-based move step for
`bayesianDynamicFilter`

. This can use two types
of stopping rules: number of iterations or number of
accepted moves for the X particles. The former is used by
default, but the latter adapts better to low acceptance
rates (sometimes with substantial computational cost). Most
updates in this algorithm are Metropolis-Hastings with
customized proposals.
