Bitcoin-Crypto-4.001

Changes for version 4.001

Public interface changes
- Bitcoin::Crypto::Transaction:
  - added block attribute
  - added is_coinbase method
  - added params argument to from_serialized method
- Bitcoin::Crypto::Block:
  - added clearer to merkle_root attribute
  - added clearer to height attribute
  - height attribute can now be lazy built from coinbase transaction in version 2 and above blocks
Improvements and behavior changes
- block and transaction deserialization performance has been greatly improved
- checking bytestrings in various function inputs has been optimized
- adding a transaction to a block now sets the block attribute in the transaction
- calling update_utxos on a transaction now sets block in utxo if transaction has a block
- coinbase transactions are now verified using a simplified procedure:
  - general format of the coinbase transaction is verified
  - some details, most notably block subsidy, are currently not verified
  - verification requires a block to be set in the transaction
- deserializing a block now validates the coinbase transaction
Deprecations
- passing block through the parameter to verify method is now deprecated in favor of set_block
