Verify() was being called by caller after the data has been successfully read after io.EOF. This disconnection opens a race under concurrent access to such an object. Verification is not necessary outside of Read() call, we can simply just do checksum verification right inside Read() call at io.EOF. This approach simplifies the usage.
