This pull request contains improvements to parser re-usability.

Highlights-

  • Perform I/O inside a new "Parser" class
  • Include escpos-php as dependency to pass a CapabilityProfile available to command parsers for later use (eg text encoding).
  • Added a new esc2html command, which repeats the esc2text command, but HTML output.
