Added Brebion et al., SCIA 2023

I have added our newly published paper on dense depth estimation to the list.

I have put it under the "Monocular depth estimation" category, which seemed the most fitting, but which is not entirely correct since we fuse events and LiDAR data; do not hesitate to notify me if you want me to move it to another category.

Thanks. Eventually, we will need to create new sections/subsections to consider sensor fusion with LiDAR, etc.
