This changes the MTCA to include the public key in the pendingEntries submitted for sequencing. Upon sequencing, the subjectPublicKeyInfo structure is bundled just like Entries are bundled, and stored in tiles with the same coordinates as the Entry tiles, but at a different layer (
-2).For writing the public key tiles, we introduce Bundling and Marshaling functions specific to a new MTCPublicKey structure which wraps subjectPublicKeyInfo and facilitates null pubkey placeholders in the tile information tracked in the Frontier.
