`libpng` in vcpkg doesn't have the right patches (libpng@ed68998) to
build with universal binary support on macOS, so let's avoid building it
(we need to bump our baseline for this too)
Thanks for letting me know it was optional, Kode :)

`qrcodegen` isn't available in most repositories, package discovery
scripts for it are maintained in a different repository, and they are
bugged for Windows at least. This basically forces us into vendoring it,
which isn't cool; libqrencode seems like viable alternative used by many
more apps
