feat(add): support Tuya _TZ3210_bfwvfyx1 as TS0505B

[will-tm]

Description

This Pull Request adds support for Tuya 15W led light bulb E27 RGBCW from AliExpress.
There is currently no support for _TZ3210_bfwvfyx1 fingerprint which causes this devices to be defaulted to TS0505B_1 whose implementation is barely compatible and unable to properly control color.

Additional Info

In order to just get the color working _TZ3210_bfwvfyx1 could just be added to TS0505B_2 supported fingerprints but this new device accepts a color temperature range from 50 to 1000 instead so I took the initiative to give it its own definition.

Will do, thank you for merging!

Hi.

Prior to this addition, the bulbs were recognized as some sort of generic led controllers. This had the negative side effect that the color temperature range was limited.
Few things have changed with this addition:

1. Color temperature range is extended, but the color temperature in Kelvin doesn't match the actual color temperature.
2. There is no more a "transition time" setting in the Settings (specific) tab in z2m. I don't know if this disappeared from this particular addition or due to some other change.
3. There was some (limited) support for effects, which is now missing.

I've been struggling with this for a couple of days, but I can't get it to work.
Either I lose proper transition support or I lose brightness control at low levels (the light won't turn on at less than 15-20%)
The current implementation handles brightness perfectly, but it lacks in the transition department. Lights can still transition, but scenes and manual control in HA are instant (or fixed to whatever is set in light_profiles.csv, which is not ideal).
Using it as a tuya light, for example with tuya.modernExtend.tuyaLight, fixes the transitions, but breaks low brightness levels.
I'm hoping for someone knowledgeable to step in.
