v6.0 preview/changelog

[codemasher]

• The required minimum PHP version is now 8.2
• [breaking] The parameter $transform of the method QROutputAbstract::collectModules(Closure $transform) has been removed in favor of a method QROutputAbstract::moduleTransform():mixed|null which is called with the same parameters.
• [breaking] The property QROptions::$outputType and the related constants in QROutputInterface have been removed. The output type is now specified via QROptions::$outputInterface with the default value of QRMarkupSVG::class. (QRGdImage (custom): mime type is not properly set in base64 output #223)
• Added XML output QRMarkupXML including an XSD schema qrcode.schema.xsd
• QRStringJSON overhaul, similar to XML output, including a JSON schema qrcode.schema.json
• Added QRGdImageAVIF for avif support
• Added QRInterventionImage (intervention/image) output
• QRFpdf::dump(): allow using external FPDF instance
• Extracted CssColorModuleValueTrait and RGBArrayModuleValueTrait for use in custom output classes
• Added PHPBench to run benchmarks (the results can be found in the benchmark branch)
• The magic setter for QROptions::$eccLevel now also accepts the string values L, M, Q, H (case-insensitive) - these will be converted internally to the respective integers. (EccLevel::fromString() #160)
• Split QR Code reader options into separate QRCodeReaderOptionsTrait
• The QRCode constructor now accepts an iterable as options, which is handed over to a new QROptions instance internally
• Extracted QRMatrix::getBooleanMatrix() from QRMatrix::getMatrix() to remove type ambiguity, the optional parameter $boolean has been removed
• hand over finder pattern coordinates to the decoder result (readFromFile/readFromBlob result returning also the QR code coordinates inside the source image #248)
