[webauthn] Decoding TPM `certInfo` and `pubArea`?

subyraman has just created a new issue for https://github.com/w3c/webauthn:

== Decoding TPM `certInfo` and `pubArea`? ==
Hello! In exploring Windows Hello with WebAuthn I find myself stuck at the verification procedure for the TPM attestation statement. The spec tells me to verify members of `certInfo` and `pubArea` but from reading I'm not entirely certain how to perform the correct decode on the bytes provided. The TPMS spec linked is pretty difficult to parse and wasn't helpful either in terms of helping me decode the data provided.

Assuming I haven't missed the correct instructions in the spec, is this something that could be added?
