Yellow Pop LED 'neon' sign

[bettse]

Some time ago I bought a pseudo-neon LED sign from YellowPop (https://www.yellowpop.com/) and it came with a 2.4ghz remote (https://www.yellowpop.com/products/wireless-dimmer-control). At the time I dug in and somehow figured out it uses something akin to the FUT020 protocol, although the exact commands were different. I've managed well enough with that for doing on/off via cron:

# Off
0 18 * * * /opt/homebrew/bin/http --ignore-stdin http://10.0.1.98/gateways/Eric command=set_white > /dev/null
# On
40 0 7 * * * /opt/homebrew/bin/http --ignore-stdin http://10.0.1.98/gateways/Eric command=next_mode > /dev/null 

After upgrading more recently and seeing the new UI, I saw the sniffer and decided to take a moment to actually capture the various buttons:

NOTE: Device ID: 1532 = 0x5FC

button	packet
on	A5 05 FC D4 02 DC
off	A5 05 FC D4 05 DD
low	A5 05 FC D4 01 E1
mid	A5 05 FC D4 04 E3
high	A5 05 FC D4 03 E4
brightness	Packet: A5 05 FC xx 00 EE

I also took a swing as the basics of on/off/brightness, based heavily on the FUT020. I wanted to open a PR for your consideration, and to make it available to others. Please let me know what you think.

Also, let me know if there is a command to correct formatting, I'm concerned I may have some parts that are wrong.
