Support BaconQrCode v3

[rossbearman]

Extends the BaconQrCode dependency to ^2.0|^3.0.

The only breaking change with v3 is dropping support for PHP versions below 8.1.

any update?

@emmanpbarrameda If you need this in the short term, you can switch to my branch to get support for this:

In composer.json:

    "repositories": [
        {
            "type": "vcs",
            "url": "https://github.com/rossbearman/simple-qrcode"
        }
    ],

And then update the version of the simplesoftwareio/simple-qrcode to dev-baconqrcode-v3

    "require": {
        "simplesoftwareio/simple-qrcode": "dev-baconqrcode-v3",
    }
