[Diff since v0.8.0](v0.8.0...v0.8.1)

**Merged pull requests:**
- Move planar_contour out of extension (#349) (@blegat)

[Diff since v0.7.8](v0.7.8...v0.8.0)

- Dependencies on JuMP.jl, RecipesBase.jl, and GeometryBasics.jl were moved to
  weak dependencies on Julia versions supporting package extensions, i.e. v1.9
  and above. On v1.10 this reduces installation time by 15% and load time by
  18% (see [#328]).

- `JuMP.optimizer_with_attributes` is no longer exported. Call it from JuMP.jl instead.
- The following change is only breaking on Julia v1.9 and above:
  `Polyhedra.Mesh` is now implemented in a package extension requiring
  GeometryBasics.jl. It is sufficient to load your plotting package, i.e.
  Makie.jl or MeshCat.jl, **before** calling `Polyhedra.Mesh`
