`N=1` pyramid node connectivity is broken

```julia using StartUpDG N = 1 rd = RefElemData(Pyr(), N) md = MeshData(uniform_mesh(rd.element_type, 2), rd) ``` gives ```julia ERROR: BoundsError: attempt to access 3-element Vector{Int64} at index [[1, 2, 0]] Stacktrace: [1] throw_boundserror(A::Vector{Int64}, I::Tuple{Vector{Int64}}) @ Base ./abstractarray.jl:737 [2] checkbounds @ ./abstractarray.jl:702 [inlined] [3] view @ ./subarray.jl:184 [inlined] [4] maybeview @ ./views.jl:148 [inlined] [5] dotview @ ./broadcast.jl:1244 [inlined] [6] build_node_maps(rd::RefElemData{…}, FToF::Matrix{…}, Xf::Tuple{…}; tol::Float64) @ StartUpDG ~/.julia/dev/StartUpDG/src/connectivity_functions.jl:157 [7] build_node_maps @ ~/.julia/dev/StartUpDG/src/connectivity_functions.jl:115 [inlined] [8] MeshData(VX::Vector{…}, VY::Vector{…}, VZ::Vector{…}, EToV::Matrix{…}, rd::RefElemData{…}; is_periodic::Tuple{…}) @ StartUpDG ~/.julia/dev/StartUpDG/src/MeshData.jl:337 [9] MeshData @ ~/.julia/dev/StartUpDG/src/MeshData.jl:324 [inlined] [10] MeshData @ ~/.julia/dev/StartUpDG/src/MeshData.jl:221 [inlined] [11] MeshData(::Tuple{…}, ::RefElemData{…}) @ StartUpDG ~/.julia/dev/StartUpDG/src/MeshData.jl:218 [12] top-level scope @ Untitled-6:10 Some type information was truncated.
