feat(setup.sh): Enhance script flexibility and user experience

- Added support for using the current directory as the root for Conda environments with the '--current-dir' option.
- Implemented automatic detection of previously used installation directories to avoid user memory overhead.
- Introduced the '--reinstall' option to allow easy reinstallation of the Conda environment, regardless of the directory.
- Enhanced argument parsing for robust handling of new and existing options.
- Improved feedback to users with informative messages about detected or chosen directories.
- Ensured seamless fallback to the default Conda directory if no custom directory is detected.
- Updated dependency checks to avoid unnecessary installations, speeding up subsequent runs.
- Maintained backward compatibility for users who prefer the default Conda setup.
- Simplified environment activation with '--activate', providing clear deactivation instructions.
