Aqara LED Strip T1

[ebaauw]

Add initial support for the Aqara LED Strip T1, see #7200.

Aready working:

• Regular control through state/on, state/bri, state/ct, state/xy, and state/alert;
• Music sync through state/music_sync;
• Setting length through config/color/gradient/pixel_count;

Still to do:

• Dynamic effects through state/effect;
• Gradients through state/gradient.
• Somehow the legacy code is still interfering with the DDF.
  • manufacturername is sometimes exposed as "LUMI", even though _Manufacturer Name_ is "Aqara"`;
  • state/effect is exposed, even though it's not included in the DDF.
  • Color Loop Active is being called, even though the LED Strip T1 doesn't support this attribute.
  • Added a check on device type Color Dimmable Light and empty Manufacturer Code, Manufacturer Name, and Model Identifier to prevent state/effect from being exposed. This also stops the polling of Color Loop Active. Somehow, addLightNode() is called way too early, before any of this info has been read and before the Device is created, so I cannot even check for a managed device.

Is it possible to set strip lenght (without aqara hub) if I add an 1m extension kit ? If yes how ? Thk
