[webauthn] Merged Pull Request: Add more requirements for ClientDataJSON serialisation.

equalsJeffH has just merged agl's pull request 1375 for https://github.com/w3c/webauthn:

== Add more requirements for ClientDataJSON serialisation. ==
ClientDataJSON is currently defined to be the JSON encoding of the
CollectedClientData. This implies that validators require a full JSON
parsing library to check needed entries in the ClientDataJSON such as
the challenge, type, and origin.

This is a problematic dependency in some cases. This change seeks to
address that by being stricter about the encoding, while still
generating JSON. Thus existing validators do not need to change but
those Relying Parties' webapps that are willing to require the use recent 
WebAuthn-implementing browsers can avoid the full generality of JSON.
