Update NanoSVG CMake recipe
Update MshIO to fix linking warning
Update PortableFileDialog to fix macOS file filtering bug
Fix Doxygen documentation

Function unify_index_buffer() now supports SurfaceMesh objects
Added compute_facet_normal() for SurfaceMesh objects
New mesh conversion utilities in <lagrange/mesh_convert.h>:
- to_surface_mesh_copy()
- to_surface_mesh_wrap()
- to_legacy_mesh() (will always copy)
Added ref_vertices() and ref_facets() methods to the legacy Mesh() class, to allow wrapping as non-const buffer in the new SurfaceMesh class.
Added an overload to SurfaceMesh::initialize_edges() that uses a callback function to specify an arbitrary ordering.
Added utility functions reshaped_view and reshaped_ref to view a single-channel attribute as a 2D matrix for regular meshes, similar to how facet_view works.

Open + save file dialogs now support WebAssembly
New abstract class representing path object. This class uses RAII to transparently handle cleanup operations required by the WebAssembly implementation of open/save dialogs, e.g.:
- Remove object from tmp file system on destruction
- Download output file on destruction
