Remove Meshes.jl and bump Julia min version

To update to the newest version of the dependencies, specifically
ImageProjectiveGeometry.jl, the minimum Julia version has been bumped to
1.9
Meshes.jl has been removed as a dependency, as it was only used to
provide the `Point3` type and introduced a lot of overhead and
additional dependencies.
The result is significantly less dependencies
