Fixed Base.copy for VNTAccumulator and TSVNTAccumulator to also copy the acc.f field, not just acc.values.
This makes sure that the accumulator is thread-safe if acc.f contains some mutable state.

DynamicPPL now allows you to set the type that log-probabilities are initialised with, using the DynamicPPL.set_logprob_type! function.
This records a compile-time preference so requires restarting Julia to take effect.

This allows model log-probability accumulation to work with different numerical precisions.
For example, if your model is defined using distributions that are parameterised by Float32 only (and avoid promoting them to Float64 elsewhere in the model), and you call DynamicPPL.set_logprob_type!(Float32), the resulting log-probabilities will also be Float32.

Previously, DynamicPPL would automatically choose a Float64 log-probability, causing any lower-precision model to be promoted.

The function DynamicPPL.get_input_vector_type(::LogDensityFunction) is now exported, in order to help with querying the type that log-probabilities are initialised with.

DynamicPPL.typed_identity is deprecated; please use Bijectors.VectorBijectors.TypedIdentity() instead (it does the same thing).

Fixed densify!! not recursing into VarNamedTuples or ArrayLikeBlocks inside PartialArrays.
Previously, nested PartialArrays buried inside these types were never visited, so they were not densified even when fully filled.
