* This library creates QR Code symbols, which is a type of two-dimension barcode.
* Invented by Denso Wave and described in the ISO/IEC 18004 standard.
* A QR Code structure is an immutable square grid of dark and light cells.
* The library provides functions to create a QR Code from text or binary data.
* The library covers the QR Code Model 2 specification, supporting all versions (sizes)
* from 1 to 40, all 4 error correction levels, and 4 character encoding modes.
*
* Ways to create a QR Code object:
* - High level: Take the payload data and call qrcodegen_encodeText() or qrcodegen_encodeBinary().
* - Low level: Custom-make the list of segments and call
* qrcodegen_encodeSegments() or qrcodegen_encodeSegmentsAdvanced().
* (Note that all ways require supplying the desired error correction level and various byte buffers.)
