[FEATURE] YTMD v2 Support

[JoshuaWowk]

Feature
Context: ytmdesktop/ytmdesktop#1139

YTMDesktop (YTMD) has announced v2 (see above) and v2 is in active development. The changes of v2 include a backwards-incompatible companion server. This implies that the current version of the plugin would be incompatible with YTMD v2. This is a feature request for YTMD v2 support.

Solution
YTMD v2 compatibility of this plugin

Alternatives
N/A

Anything else?
API documentation of the new companion server
Also, I'm hoping nobody minds that I copied this issue, nearly in its entirety, from here: XeroxDev/YTMD-StreamDeck#85

@JoshuaWowk thanks, the ytmd new version now using socket.io implementation, and none of usable go library are working for this case, if stick with restapi, there are rate limit that cannot exceed more than 1 call per 5sec. So, i need to workout the socket.io first before jump into the ytmd-remote.
