weightings for new samplers need to be made for permutationsToSamples

[AdityaSavara]

With astroidal and shell, the samplings are done correctly now, but the permutations to samples feature is not yet compatible with those features in a correct way. Permutations to samples can be used with those features, as long as the logP are normalized to the non-ergodic sampling. See the Document 0-Example00f
