* llava: add requirements.txt and update README.md This commit adds a `requirements.txt` file to the `examples/llava` directory. This file contains the required Python packages to run the scripts in the `examples/llava` directory. The motivation of this to make it easier for users to run the scripts in `examples/llava`. This will avoid users from having to possibly run into missing package issues if the packages are not installed on their system.
