7d7676beda attest: move public key parsing server side 
Event log parsing requires knowning both the public key and signing
parameters. Symmantically, this information should be from an attested
public key blob, not additional data passed by the client.

Introduce a new method for parsing an AIK's public key blob, returning
a new AIKPublic struct.

833a7e119f attest: remove unused KeyPurpose exported type 
Was going through the godoc and it's not clear that this is ever used.
To clean up the API, remove KeyPurpose for now. This could probably be
an internal validation anyway, right?

2464131d7c Add a Public() method to the AIK that returns a public key (#55) 
We plan to identify AIKs based on their public key. The raw blob should
be available via the AttestationParameters, but we hope that users will
only use that struct for generating challenges.

Because this parses the public key on AIK creation and loading, this PR
should have existing coverage.
