Static table for access-control-request-headers (index 80)

[tcfw]

Found an issue when trying to use CORS via HTTP3 (lucas-clemente/quic-go) that the "allow-control-request-headers" was being interpreted as the "allow-control-expose-headers" when the request was coming from chrome 86.0.4240.111 and firefox 82.0.

I've checked the most recent draft-ietf-quic-qpack-19 and found in the static table that it should be coming in as index 80 but looking here it's paired with index 79.

You mean that this line is incorrect, right?
https://github.com/marten-seemann/qpack/blob/f1218f693233709a863ecf6097f6aa639f58d200/static_table.go#L84

Would you mind sending us a PR to fix it (both in this line and in the encoderMap table)?

That's the one, I believe.

Will send through shortly.
