Subject: [PATCH 1/2] Support new sequence file formats and improve error
 handling

Add support for .gbff and .gbff.gz file extensions in sequence reader.

Update the logic to return an error instead of using NilIBioSequence when no sequence files are found, improving the error handling and user feedback.
