Re: [mh] Nanoleaf Aurora crashes on latest master

No worries Howard,

I don't think the issue was with the Nanoleaf_Aurora module itself. I 
had been using the same version of the module on MH 4.2 and didn't have 
any issues. It must have something to do with the JSON parser used by MH 
that differs between the versions. I haven't had a chance to check if it 
is using the fallback parser module packaged with MH, or is using the 
system level one. In any case, using JSON::XS in my other modules solved 
this for me.

On another related subject, what are your thoughts about generic module 
extensions for lights that support RGB, color temperature and effects? 
Having a standard interface to control the common features on the 
increasing number of devices that support one or more of these features 
like Nanoleaf Aurora, Yeelight, Phillips Hue, WLED, ESPixelStick, FPP, 
etc seems to make sense. I started working on FPP and ESPixelStick 
integration with MQTT and realized that each of these modules needed 
RGB<->HSV conversion routines and common conversion things like this 
would make more sense to have in a parent class.
