fix(bin/mpvctl)!: remove potentially faulty nc, use socat (#26)

* ci(lint.yml): install required `socat` dep

* fix(bin/mpvctl)!: remove potentially faulty `nc`, use `socat`

there are a plenty of `nc` flavours out there,
and not all support `-U` flag to communicate with unix-socks

BREAKING CHANGE: `socat` required dependency

* fix(ytdl-mpv): update required deps (s/nc/socat)
