blockchain_converter: Add support for batch transactions

Add log level support.

Add testnet support.

Add command-line options:
  --help
  --data-dir
  --testnet-data-dir
  --testnet
  --log-level
  --batch
  --batch-size
  --block-number

See help for usage. Run at log level 1 to see profiling stats.
