[Bug] Lonsonho Tuya 2 gang dimmer not working as expected
**Describe the bug**
Recently got a [Lonsonho QS-Zigbee-D02-TRIAC-2C-LN](https://www.zigbee2mqtt.io/devices/QS-Zigbee-D02-TRIAC-2C-LN.html), which is a 2 gang dimmer.
This exposes 2 "endpoints" meaning that there are two additional topics, one for each  connection (`l1` and `l2`).

**Current behavior**
After some fiddling around I ended up with 3 services in HomeKit: one that controls the brightness of one of the lights and two that control the state of one of the lights (but these do not really seem to work).

**Expected behavior**
One on/off + brightness control for each light/endpoint.

**MQTT messages**
On each topic (`l1` and `l2), a `state` and `brightness` property is available.

**Versions used**
