  Represent binary data as ArrayBuffers instead of base64-encoded DOMStrings (#77)

* Represent binary data as ArrayBuffers instead of base64-encoded DOMStrings

Fixes #61.

I switched the main API completely from base64-encoded DOMStrings to
Buffersource (for input parameters) and ArrayBuffer (for output
parameters). The actual signatures are still computed over the same data
as before, so signatures computed after this change will be compatible
with those computed before, except for being represented differently.

I moved the ClientData section into the Authenticator model section
since it is not directly used by script authors. This structure still
does base64 encoding of the challenge, for two reasons. First, this
maintains backward compatibility. Second, it is more natural to
represent a binary challenge in JSON as base64 rather than the clunky
array notation.

I would like to advocate for also changing the rawData in the TPM and
packed attestation formats to ArrayBuffers so we can sign directly over
the data without base64 encoding. That would seem to simplify
processing. However this would break compatibility so I would like to
gather opinions from the group before making that change. On the bright
side, I do not know of any implementations producing WebAuthn
attestation statements in these formats yet.

* Remove base64 from packed and TPM attestation formats

Remove base64 encoding from the rawData fields and return them directly
as ArrayBuffers.

* Clarify Android attestation procedure

  Simplify attestation structure by moving details into authnr model (#76)

* Simplify attestation structure by moving details into authnr model

Moved most of the attestation details into the authenticator model
section, and flattened the structures for simplicity. Updated spec
language to match.

It may be possible to further simplify the attestation details in the
authenticator model section, but I would prefer that an attestation
expert weigh in on that.

Also a few other small formatting fixups.

* Incorporate feedback from JeffH

* Rebasing to master after merge of PR#77

* Simplify Android attestation by removing manipulation of SafetyNet responses

* Incorporate feedback from JeffH, fix an incorrect section level
