Independent Rhino Obj -> Compas Obj converter based on rhino3dm

# Feature Request

As a [role], I want an independent converter so that I can convert Rhino Obj -> Compas Obj outside Rhino Env.

## Details

**Is your feature request related to a problem? Please describe.**
With the [Hops](https://github.com/mcneel/compute.rhino3d/tree/8.x/src/ghhops-server-py) plugin, users are able to send Rhino Object to a remote / local HTTP server and process all computation outside Rhino. (whether it is geometry related or not).

However, if main computation is conducted with `compas`, we need to convert Rhino Object to Compas Object now outside Rhino, whereas the [conversion functions](https://compas.dev/compas/latest/api/compas_rhino.conversions.html) provided by `compas_rhino` has to be run inside a Rhino Environment.

**Describe the solution you'd like**
While McNeel provides open-sourced [rhino3dm](https://github.com/mcneel/rhino3dm) for basic Rhino Obj processing, it is possible to conduct whole computation/conversion outside Rhino Environment, and only use Rhino as Input + Visualizer.
It is possible to remove the dependency of `Rhino` module for `compas_rhino.conversion`, and allow users to convert objects in pure Cython environment.

**Describe alternatives you've considered**
Additional python script to convert Rhino Obj inside GH before connecting to Hops. Though not ideal.
