* rgb(w) bulbs: fix hue/saturation conversion
The attributes used to report Hue and Saturation can have a value of
0-254. We want to translate this to a percentage of 0-100%. The HA
DTHs were dividing by 255 instead of the correct value of 254. Because
the wrong divisor was used the result would be off by a percent about
25% of the time. The ZLL DTHs had the same bug plus they were also
multipling the Hue by 360 instead of 100.
* rgb(w) bulbs: set hue & saturation in a single command
Previous two commands were being used to set Hue and Saturation. Now
a single command is used and a transition time of 0 so the color changes
must faster.
* Don't rely on reporting for hue, saturation and color temperature
Previously we were configuring the RGB(W) and Color Temperature bulbs
to report any Hue, Saturation and Color Temperature changes. Now we
manually read these attributes any time a command is executed that
changes them.
This is because ZLL bulbs do not report or allow for configuration of
reporting of attributes. As a result if we change a value, we have to
manually call a read of that attribute to update our status.
