Features added:-
Thread Safety: Access to the normalStore is protected with a normalStore_lock to ensure that updates are thread-safe.
Duplicate Count: Each file hash tracks how many times the same file (with the same hash) has been added.
Timestamps: A timestamp is stored when the file is first added, allowing you to track when the file entered the system.
File Removal: Added a remove_file function that removes the file from the metadata and deletes the entry if no files are left.
