Aitviewer

Minor release to fix imgui version as described in 24 .

Changelog:
- New remote viewer API for two-way communication (see new `remote_two_way_communication.py` example).
- New renderable `SDF` for visualizing level sets of a dense SDF volume (see new `load_sdf.py` example).
- Added new `get_mask_ids()` method to `HeadlessRenderer`, and added `color_map`and `id_map` parameters to `get_mask()`.
- `Lines` can now be rendered with a different colors for each line segment.
- Updated export GUI with new rotation control and export quality settings.
- New mesh clipping fields for visualizing the interior of a mesh (`mesh.clip_control` and `mesh.clip_value`).
- Added `transformed_vertices` and `current_transformed_vertices` properties to `Meshes`.
- Added camera movement with constant speed regardless of zoom level (holding `ctrl` + scroll wheel).
- Added window icon to the viewer.

Bug fixes:
- Fixed a bug that caused clicking on point clouds to select them to not work.
- Added missing `bounds` property to `BoundingBoxes` renderable.

* Pull request in preparation for 1.8.0 release by ramenguy99 in https://github.com/eth-ait/aitviewer/pull/23

**Full Changelog**: https://github.com/eth-ait/aitviewer/compare/v1.7.1...v1.8.0

Changelog:
- New Remote Viewer API that allows sending data for visualization to a viewer running remotely (see the examples `remote.py` and `remote_custom_viewer.py`). The Remote Viewer can also be run locally to enable non-blocking code execution.
- New official documentation page: [https://eth-ait.github.io/aitviewer](https://eth-ait.github.io/aitviewer/)
- Added a new joint edit mode for SMPL that rotates joints around their local axes instead of using euler angles.
- Billboards can now be created from numpy arrays and PIL images.
- Removed `config` parameter from the `Viewer` constructor, configuration should now be updated with `C.update_conf()`.
- Added support for exporting videos in `.webm` format with transparent background.
- Updated [3DPW ](https://github.com/eth-ait/aitviewer/blob/main/examples/load_3DPW.py) example.
- Updated the codebase to use isort and [black ](https://github.com/psf/black) formatting.
- **Full Changelog**: https://github.com/eth-ait/aitviewer/compare/v1.6.1...v1.7.0

Bug fixes:
- Fixed a bug that only allowed for a limited number of face colors in the Meshes class.
- Fixed a bug that caused image and video export on retina displays to have double resolution.

Some hot fixes for v1.6.0.
