Class Blob

The Blob type is a length-prefixed field with arbitrary data.
Two common fields that use this type are SigningPubKey and TxnSignature, which contain (respectively) the public key and signature that authorize a transaction to be executed.
Blob fields have no further structure to their contents, so they consist of exactly the amount of bytes indicated in the variable-length encoding, after the Field ID and length prefixes.
