Audit Merkle Proof

[dgarcia360]

Trees stored per block:

• Transactions
• State tree (merkle path not implemented in REST) (treat in a separate issue)
• Receipts

Proposal

Check if a transaction is included in a block

blockHttp
    .getTransactionMerkleAuditProof(height: uint, hash: string)
    .subscribe( merkleAuditProof => {    
        // Returns Observable<MerkleAuditProof>   
        console.log(merkleAuditProof.isConsistent()););
     }

Repeat for receipts.

this is kind of implemented in https://github.com/nemtech/nem2-sdk-typescript-javascript/tree/task/T516/merkle-tree - some changes are required

@rg911 please have a look here; do we have the needed methods in the SDK now ?

If not, please prioritize integration of this 👍

For receipt Merkle Proof, we need to serialize receipt object and hash it to be able to query the rest endpoint. Hash algorithm can be find out in https://github.com/nemtech/catapult-server/blob/8467be1485db44d60a9704ddf2eeab9050273911/src/catapult/model/ResolutionStatement.cpp#L48. Serialization will be integrated in to catbuffer
