The addition of Manifold to types caused problems with the Transducers.tcollect function which crashes the compiler when used with very complex types.
MWE:

julia> using Meshes

julia> using Random; Random.seed!(123);

julia> r = rand(Ring);

julia> gset = GeometrySet([Multi([PolyArea(r)])]);

julia> gset |> Translate(1, 1, 1)

In this PR, I replace the tcollect function with a vector comprehension as a temporary solution.
