Added Added pluggable function trimesh_slice in compas_rhino. Added equality comparison for pointclouds. Added compas.data.is_sequence_of_uint. Added general plotter for geometry objects and data structures based on the artist registration mechanism. Added support for multimesh files to OBJ reader/writer. Added support for attaching and detaching meshes in compas.robots.RobotModelArtist and drawing them. Added meshes method to artists of compas.robots.RobotModel. Added FrameArtist class to compas_blender. Changed compas.robots.Axis is now normalized upon initialization. Fixed a bug in compas.numerical.dr_numpy when using numpy array as inputs. Allowed for varying repository file structures in compas.robots.GithubPackageMeshLoader. Fixed data schema of compas.geometry.Polyline, compas.geometry.Polygon, compas.geometry.Pointcloud. Fixed Configuration.from_data to be backward-compatible with JSON data generated before compas 1.3.0. Changed compas_rhino.drawing.draw_breps to assume provided polygon is closed and automatically add missing corner to polycurve constructor. Changed conversion of edges and faces to uniques keys for the data dicts to use the string representation of a sorted tuple of identifiers. Added dtype to JSON decoding error message.
