Fix PHP 8.1 deprecation

[jmsche]

Hi,

This fixes a minor deprecation in 4.3 branch for PHP 8.1.

Without this here is the risen deprecation:

Deprecated: strtolower(): Passing null to parameter #1 ($string) of type string is deprecated

Hey, this has already been fixed in #97, it's not tagged yet though.

Hi, sorry, didn't see it :) Could you please create a tag so it's available? Thanks!

I will as soon:tm: as i'm done with the v5 branch as there are a bunch of things i want to backport to 4.x. In the meantime I'd advise to manually set QROptions::$dataModeOverride = '' or suppress E_DEPRECATED.

@menjilx Your fix won't do anything because you always set the value of $dataModeOverride to '' now, like, it can't even be changed if you wanted to because $interface will now always yield null. Just set it to an empty string wherever you invoke the QROptions instance.

thanks for checking my response, also updated it and placed it on the "options" already.

I have tagged the fix now as a release as i currently don't have time for the other things i've planned. It's available as 4.3.3.
