This file should be removed from the project, since composer generates it at install time.

Argument parsing is modified to add a --debug option.
This is to help debug any file parsing problems.

Since $data and $datasize are protected members of the superclass, they must not be redeclared here.

The placeholder for all 2D codes except for QR codes.

Removed since I needed the width to be exactly 80mm.

This is probably not useful at all for escpos-tools, since there is no bidirectional communication going on.

MicroQR codes are not supported in chillerlan/php-qrcode

This PR backports the QR code parsing and rendering routines developed for the gilbertfl/escpos-netprinter project.
It resolves the feature request in #59. Since it is compatible with PHP 8.4, this PR should supersede the PHP8 conversion from the PR related to #76 and resolve the problem in #82.
To do the rendering of the QR codes, a new dependency is introduced: the chillerlan/php-qrcode library, which itself depends on composer, mbstring and imagick.
This PR has been cut down to only the files that are necessary, since the escpos-netprinter project is more of a derivative than a fork. This note is important since I DO NOT propose to remove any files in escpos-tools (like the licence or CONTRIBUTING files).
The only binary blob in this PR is the "NoQR.jpg" file: this is a QR code that encodes the string "No QR code here!". This QR code is substituted when a badly-behaving input demands printing a code before it's data has been stored. It is used esc2html.php at line 140.
