Currently in the ZipFile class implementation, when processing the zip file headers "extra" field, a .read() call is used without using the returned value in any way. This call could be replaced with a .seek() to avoid actually doing the IO.

The change would improve performance in use cases where the fileobject given to ZipFile is backed by high latency IO, eg. HTTP range requests.
