Moode Audio remote MPD client (display) with M5 Core2

My Moode RPI players do not have a display, so I added a remote one, that allows me to:

- load the initial/updated config from SD and save it to flash (NVS)
- select the MPD player from a list if you have more than one player (I do)
- see what's currently playing
- select a favourite radio station from a list of favourites (configured in Moode or not, the url is all that MPD needs)
- stop/start playing

I suppose it would work with any MPD based audio player.
