ProgressLoggingFoldable missing size method

[sethaxen]

To use withprogress with Folds.jl, the method size needs to be implemented for it.

julia> using Folds, Transducers

julia> Folds.collect(withprogress(1:3))
ERROR: MethodError: no method matching size(::Transducers.ProgressLoggingFoldable{UnitRange{Int64}})
