PR Feedback

• 💡 General suggestions: While the goal of reducing dependencies is commendable, it's important to ensure that the functionality of the application is not compromised. If htslib was handling critical tasks, alternatives should be provided. Also, instead of commenting out the code, it would be better to remove it to keep the codebase clean.
