LinkPlay devices discover

[Limych]

Please add discover of LinkPlay media player devices.

Here is an example of a real mDNS entry that such device leaves:

_raop._tcp.local.
	PTR 00226C346694@Kitchen._raop._tcp.local. ar: 00226C346694@Kitchen._raop._tcp.local.
	TXT "txtvers=1" "ch=2" "cn=1" "ek=1" "da=true" "sm=false" "et=0,1" "md=0,1,2" "pw=false" "sv=false" "sr=44100" "ss=16" "tp=UDP" "vn=65537" "vs=115.2", GGMM_E3_6694.local.
	A 192.168.1.80, 00226C346694@Kitchen._raop._tcp.local.
	SRV GGMM_E3_6694.local.:4515 0 0, 00226C346694@Kitchen._raop._tcp.local.
	NSEC, GGMM_E3_6694.local.
	NSEC

I am engaged in the support of component for the Home Assistant for these devices. The autodiscovery feature will be extremely useful for users.
