Get rid of the logic to read the metadata from the header of the safetensors file manually and use the functions as part of safe_open() to get the metadata. This is much cleaner and allows us to not rely on our own custom methods to get metadata, but use safetensors provided APIs Differential Revision: [D79460272](https://our.internmc.facebook.com/intern/diff/D79460272/) [ghstack-poisoned]
