Add Support for FUT021 Remote

[pro100filimon]

Hello! Could you please add support for the FUT021 remote? This is a simple brightness-adjustable remote. Using a sniffer, I’ve decoded how it works.

In the 6-byte sequence, the last byte simply increments by one. It could probably be randomized—but it must differ from the previous value.

Button Commands:
A5 50 FF E0 05 — Off

A5 50 FF E0 02 — On

A5 50 FF E0 01 — Min Brightness

A5 50 FF E0 04 — Medium Brightness

A5 50 FF E0 03 — Max Brightness (also acts as Pair/Unpair)

Brightness Levels via Rotary Control:
A5 50 FF 99 00 — Minimum Brightness

A5 50 FF C9 00 — 25% Brightness

A5 50 FF E6 00 — Mid-Level Brightness (~50%)

A5 50 FF 3F 00 — 75% Brightness

A5 50 FF 75 00 — Maximum Brightness

Would be great to have this integrated! Thanks in advance.
