piv: mark PC/SC connection as exclusive #51

Since this package holds onto a transaction, ensure other calls to Open exit immediately instead of hanging.

Updates #45 Updates #47

Going to merge this for now since the YubiKey does require an exclusive transaction. If we figure out how to address #47, we can move it back to shared.
