MMDetection3D v1.1.0 Release

We are excited to announce the release of MMDetection3D 1.1.0 as a part of the OpenMMLab 2.0 project! Compared with version 1.0.0, MMDetection3D 1.1.0 introduces an updated framework structure for the core package and a new section called Projects. Specifically, we have significantly refactored the core package's code to make it clearer, more comprehensible, and disentangled. The new Projects section serves as an essential addition to MMDetection3D and supports flexible code contribution without strict code requirements, enabling faster integration of state-of-the-art models and features. To help users migrate from version 1.0.0 to 1.1.0 as smoothly as possible, we have prepared a migration guide. Any questions about migration are welcome to be posted on issue。
