Support for new device ZG-227Z

[pohlond]

Hello, I have successfully added support for the new device ZG-227Z. It is a different variant of the TH03Z sensor. The temperature/humidity sensor is AHT20 and is connected via software I2C. MCU is TLSR8253.

According to the original firmware, the manufacturer is 0x1286 and the image type is 0x0203.

// GPIO_PA7 - SWS
// GPIO_PB1 - TX
// GPIO_PC2 - LED
// GPIO_PB7 - RX
// GPIO_PD4 - KEY
// GPIO_PC3 - SDA
// GPIO_PC4 - SCL

Patch file:
ZG_227Z.zip

So the PCB serves as a template for multiple types of devices, nice...

1. Original name in z2m/ZHA - TS0601_TZE200_???? ?
2. Original Full-Flash ?
3. Zigbee OTA ID: 1286-0203-10013001 ?

ZigbeeTlc version has been added. https://github.com/pvvx/ZigbeeTLc

I soldered AHT25 into ZG-103Z and tested it...

Same firmware works on ZG-227ZS v1.2
But instead of TLSR8253 it has TLSR8258. It announced itself with the same name.
I tried to port it, but couldn't make the sensor work.
Unfortunately, the backup i took is most likely corrupted somehow, because when i tried to flash it back it didn't work. So i set it aside and forgot about it until now.

It doesn't matter. The main thing is that the port pins match.
