[Feature request] Accept piped file paths in CLI

[nx10]

Hi,

I’d like to request a feature for bids2table that allows the CLI to accept file paths via standard input (stdin) instead of requiring a root directory. This would make it easier to work with file paths from various sources like cloud storage or environments where direct access to the entire directory is limited.

Examples:

1. Cloud storage:

   aws s3 ls s3://my-bids-dataset/ --recursive | awk '{print $4}' | bids2table

2. Integration with other tools:

   find /my/data -type f -name "*.nii.gz" | bids2table

3. From a file:

   cat bids_file_paths.txt | bids2table

4. Limited access:

   echo "/restricted_path/sub-01/anat/sub-01_T1w.nii.gz" | bids2table

Let me know what you think!

Thanks!
