Blickfeld-scanner

Added
* Protocol: Additional processing section in advanced configuration
* Example for builds with external projects which locates all dependencies in a local directory. Can be found in cmake/external. Install section in documentation is updated.

Changed
* Bugfix: M_PI was not defined and compiler flags were overridden in cpp windows builds

Added
* Python: Flag for detecting frame losses

Changed
* Change default scan pattern to 40 scanlines up, 40 scanlines down, INTERLEAVE pulse type, and COMBINE_UP_DOWN pulse frame mode
* Bugfix Python: Fixed and simplified the recording functionality. The compression level can now be adjusted and is default set to 1.
* Protocol: Formatted protobuf files for better readability
* Python: Follow PEP 8 version rules

Added
* Python: Example of frame export for matlab / octave
* [Introduced in firmware v1.10] Add filter parameters to scan pattern. It allows to increase the number of returns per point and provides min/max filters for point attributes. The filter can be overridden during a stream request.
* [Introduced in firmware v1.11] Add preliminary noise filter configuration to scan pattern
* Protobuf: Add internal message option to trigger export of custom targets
* CI: Provide test coverage
* [Introduced in firmware v1.11] Interleave frame mode, which allows to double the horizontal density with the COMBINE_UP_DOWN FrameMode and efficiently uses the down-ramp phase in the inner horizontal FoV
* [Introduced in firmware v1.11] Add API request for advanced configuration

Changed
* Bugfix: Removed incorrect end of line prints in cpp fetch_clouds example

Changed
* Bugfix: Frame was recorded multiple times if Python writer was faster than frame receiver

Added
* Protocol: HW Variant Apollon A1 BDU
* Reference frame for depth map

Changed
* Doc: Fix rendering of python point cloud stream
* Doc: Add configure point cloud stream to python examples in the doc
* Upgrade debian testing package to libprotobuf23

Added
* [Introduced in firmware v1.9] Protocol: Request to trigger a self test of the device
- Validates the hardware, operates the device, and generates a report.
- The report is currently only accessible by developers.
- A success flag indicates if the device is functional.
* [Introduced in firmware v1.9] Configurable point-cloud stream: Used to reduce the network bandwidth and to decrease the Protobuf encoding/decoding effort
- The post-processing can be configured with a filter. It allows to increase the number of returns per point and provides min/max filters for point attributes.
- The desired frame fields in the stream can be requested by passing a reference frame. Example reference frames are available.

Changed
* CI: Improve internal release automation
