Optional logger for debug-level instrumentation of txid conversions, BEEF
wiring, and merkle path operations.

No logger is configured by default — zero overhead when unused. Consumers opt
in via:

    require 'logger'
    BSV.logger = Logger.new($stdout).tap { |l| l.level = Logger::DEBUG }
- **@return** [Logger, nil]
