Add `OrientedBoundingBox` for spatial region analysis and particle selection

[LasNikas]

This PR adds an OrientedBoundingBox that enables analysis of arbitrarily oriented rectangular regions within computational domains. For example: use is_in_oriented_box(coords, box) to define measurement windows for calculating flow rates through specific cross-sections.

Or for particle selection: using intersect(ic::InitialCondition, box::OrientedBoundingBox...) - particularly useful for creating clamped particles for the TLSPH system.

2D

using TrixiParticles
using Plots

data_dir = pkgdir(TrixiParticles, "examples", "preprocessing", "data")
geometry = load_geometry(joinpath(data_dir, "potato.asc"))

box_1 = OrientedBoundingBox(geometry)
box_2 = OrientedBoundingBox(geometry, local_axis_scale=(1.5, 2))
box_3 = OrientedBoundingBox(geometry, local_axis_scale=(3, 0.5))

plot(geometry, label="geometry", color=:black)
plot!(box_1, label="box: no scaling")
plot!(box_2, label="box: local_axis_scale=(1.5, 2)")
plot!(box_3, label="box: local_axis_scale=(3, 0.5)")

# Create a point cloud from a spherical shape (quarter circle sector)
shape = SphereShape(0.1, 1.5, (0.2, 0.4), 1.0, n_layers=4,
                    sphere_type=RoundSphere(; start_angle=0, end_angle=π/4))
box = OrientedBoundingBox(shape.coordinates)

3D

(hard to visualize but it's working)

file = pkgdir(TrixiParticles, "test", "preprocessing", "data")
geometry = load_geometry(joinpath(file, "inflow.stl"))
box_3d = OrientedBoundingBox(geometry)

trixi2vtk(stack(box_3d.spanning_vectors) .+ box_3d.box_origin)
