Get a block object given a block ID or block height.
Request:
requestType is getBlock
block is the block ID (optional)
height is the block height (optional if block provided)
timestamp is the timestamp (in seconds since the genesis block) of the block (optional if height provided)
includeTransactions is true to include transaction details (optional)
includeExecutedPhased is true to include approved and executed phased transactions (optional)
requireBlock is the block ID of a block that must be present in the blockchain during execution (optional)
requireLastBlock is the block ID of a block that must be last in the blockchain during execution (optional)
Note: block overrides height which overrides timestamp.

baseTarget (S) is the base target for the next block generation
payloadHash (S) is the 32-byte hash of the payload (all transactions)
generatorRS (S) is the Reed-Solomon address of the generating account
nextBlock (S) is the next block ID
numberOfTransactions (N) is the number of transactions in the block
blockSignature (S) is the 64-byte block signature
transactions (A) is an array of transaction IDs or transaction objects (if includeTransactions provided, refer to Get Transaction for details)
executedPhasedTransactions (A) is an array of transaction IDs or transaction objects (if includeExecutedPhased provided, refer to Get Transaction for details)
version (N) is the block version
totalFeeNQT (S) is the total fee (in NQT) of the transactions in the block
