How to load/save map functionalities and missing scripts and time analysis

[StarFyx]

Thank you for your open source code and excellent work. However I have some question about ORB_SLAM3V1.0 .

1. I wonder know how to load or save map in ORB_SLAM3 v1.0 which is mentioned in the release V1.0.
2. There is missing scripts such as ./tum_vi_examples mentioned in the README.
3. There isn't line #define REGISTER_TIMES in include\Config.h , but some empty config class about IMU, viewer and camera.
4. In the same experimental environment, ORBSLAM3-V1.0 has poor precision. For example, the following shows the result in dataset MH04:

ORBSLAM3 V1.0
compared_pose_pairs 242 pairs
absolute_translational_error.rmse 0.129154 m
absolute_translational_error.mean 0.121049 m
absolute_translational_error.median 0.115579 m
absolute_translational_error.std 0.045034 m
absolute_translational_error.min 0.021134 m
absolute_translational_error.max 0.256131 m
max idx: 69

ORBSLAM3 V0.4
compared_pose_pairs 221 pairs
absolute_translational_error.rmse 0.095110 m
absolute_translational_error.mean 0.088771 m
absolute_translational_error.median 0.084761 m
absolute_translational_error.std 0.034141 m
absolute_translational_error.min 0.014390 m
absolute_translational_error.max 0.185725 m
max idx: 70

Looking forward for reply , thank you very much.
