Update README and Add Crucial Information

[Ali-Flt]

1. You have used /mnt/9a72c439-d0a7-45e8-8d20-d7a235d02763/DATASET/HO3D_v3/ in the commands in the readme file and in the data reader script. Please change them to something like /path/to/your/dataset
2. In your docker run command you are mounting /home and /tmp and /mnt into the container. Why is this? Why would you want to mount /home into the container? This is very bad and dangerous practice.
3. Please add this to the readme because it is required to fix the GLIBCXX error:
   export LD_LIBRARY_PATH=/opt/conda/lib:${LD_LIBRARY_PATH}
4. Add minimum GPU requirements for the project to run. I spent hours building this and trying to make it to work just to find out from the previously closed issues that my GPU (3070Ti) is not enough to run the code.

It seems to me that no one has put any effort into transforming this repo from a personal repo into a public one for general use.
