Support for lumi.camera.gwagl01 camera & gateway hub

[Juwei80]

Hello!

Can we add support for the Aqara G2 Camera & Gateway HUB?
What is needed to include the HUB, can i assist somehow?
With the mihome adapter, that HUB is also not working, even with the correct token...

miio.0	2020-01-10 08:46:20.778	warn	(2813) lumi.camera.gwagl01 is not supported for now.
miio.0	2020-01-10 08:46:20.778	warn	(2813) Error: Cannot find module './Devices/Type/camera'
`

For those who don't know how to get the token, it's easy using the log file in the Mi Home App 5.4.54 mentioned in https://github.com/Maxmudjon/com.xiaomi-miio/blob/master/docs/obtain_token.md.

Best regards,
Juergen
