Remove Requires.jl

 * Removed SimpleUnpack.jl as a dependency. Loading StartUpDG.jl will no longer reexport `@unpack`, since destructuring via `(; propertyname) = x` is supported natively in Julia 1.7 and up.
 * Updated to NodesAndModes v1, which changed the ordering of triangle nodes to make them consistent with tet node ordering. 
 * We introduced a `MultidimensionalQuadrature` type. All `Polynomial` approximation types now utilize either `MultidimensionalQuadrature` or `TensorProductQuadrature` as a type parameter. The previous type parameter `DefaultPolynomialType` is now simply used to determine the default quadrature type parameter. Note that this is internal behavior and should not impact standard usage of StartUpDG.jl.
+* Removed Requires.jl in favor of [package extensions](https://pkgdocs.julialang.org/v1/creating-packages/#Conditional-loading-of-code-in-packages-(Extensions)) for Plots.jl and SummationByPartsOperators.jl dependencies.
