Issue parsing font info lib item in instance

[ryanbugden]

With the following instance lib...

      <lib>
        <dict>
          <key>public.fontInfo</key>
          <dict>
            <key>versionMajor</key>
            <integer>1</integer>
            <key>versionMinor</key>
            <integer>3</integer>
          </dict>
        </dict>
      </lib>

I get this error when trying to generate UFOs

  File "/Applications/RoboFont.app/Contents/Resources/lib/python3.12/ufoProcessor/ufoOperator.py", line 942, in generateUFOs
ValueError: too many values to unpack (expected 2)

The line seems to be here:

ufoProcessor/Lib/ufoProcessor/ufoOperator.py

Lines 938 to 943 in f3dabad

	for infoDict in [
	self.doc.lib.get("public.fontInfo", dict()),
	instanceDescriptor.lib.get("public.fontInfo", dict())
	]:
	for key, value in infoDict:
	setattr(font.info, key, value)

If I remove the lib, the error disappears.
