GET converter is failing for IKEA Tådfri LED1624G9 color bulb

[madchicken]

Hi, while using this library for a custom project, I discovered that calling the GET converter for any color attribute on the Ikea LED1624G9 outputs an UNSUPPORTED_ATTRIBUTE error.
The problem is very similar to the one reported here Koenkk/zigbee2mqtt#3260 except I am not using reporting ATM.
Maybe I didn't get how to use the converter, but I did the same test on zigbee2mqtt, and when calling GET with a payload like { color: { rgb: '' } } I get the same error printed in the console.

In toZigbee.js can you change await entity.read('lightingColorCtrl', ['currentX', 'currentY', 'currentHue', 'currentSaturation']); to await entity.read('lightingColorCtrl', ['currentX', 'currentY']);, does this fix the issue?

See https://www.zigbee2mqtt.io/how_tos/how_to_support_new_devices.html on how to modify toZigbee.js

Yes, it does. I was about filing a PR with the same fix, but I wasn't sure I was doing the right thing. I opened the issue to have a confirmation.

Merged the PR so I assume this can be closed now.
