Re: [quicwg/base-drafts] Add an appendix containing test vectors for "Initial". (#1573)

[Christian Huitema <[e-mail]>]

I think we would be better off with the test vector that EKR published. I use it as unit test in Picoquic, and the implementation works against Quicly, NGTCP2 and NGX.

Here are the values that I tested, based on EKR's message:
```

/*
 * test copied from EKR test vector
 */
