  1. new: UtlsPreSharedKeyExtension 

    In `u_pre_shared_key.go`, create `PreSharedKeyExtension` as an interface, with 3 implementations:
- `UtlsPreSharedKeyExtension` implements full support for `pre_shared_key` less resuming after seeing HRR.
- `FakePreSharedKeyExtension` uses CipherSuiteID, SessionSecret and Identities to calculate the corresponding binders and send them, without setting the internal states. Therefore if the server accepts the PSK and tries to resume, the connection fails.
- `HardcodedPreSharedKeyExtension` allows user to hardcode Identities and Binders to be sent in the extension without setting the internal states. Therefore if the server accepts the PSK and tries to resume, the connection fails.

TODO: Only one of FakePreSharedKeyExtension and HardcodedPreSharedKeyExtension should be kept, the other one should be just removed. We still need to learn more of the safety of hardcoding both Identities and Binders without recalculating the latter.
