Add DevEnum attribute support
To test please recompile TangoTest db from PR -> https://github.com/tango-controls/TangoTest/pull/8 Moreover, in tangoql please navigate to tangogql/aioattribute/attribute.py and change line:
read = await self.device_proxy.read_attribute(self.attr, extract_as=ExtractAs.List)
remove parameter extract_as it causes dev enum to fail somehow
