After the merging of https://github.com/TuringLang/AbstractMCMC.jl/pull/86. We can start removing HMC and MH samplers to using `ExternalSampler` interface. This would involve following steps: - [ ] add `getparams` and `setparams!!` implementation...

Add `getparams` and `setparams!!` following AbstractMCMC v5.5

Move `predict` from Turing, implemented using `fix`

fix #647 Turing's implementation relies on `setval_and_resample!` to generate the predictions, and use `bundle_samples` function implemented in `Turing.Inference`. This PR provides a draft implementing `predict` using the new `fix` interface:...

Add `getparams` and `setparams!!` following `AbstractMCMC` v5.5 and v5.6
