MPD mizy customization
**ATTENTION! MPD in miZy has its own peculiarities ** - we do not use any OpenWrt or other binaries, and we build it ourselves with our patches and other build options - (the main goal is to keep the smallest size - not to the detriment of the features)
added many of the experimental features that are not in the standard MPD
- webdav
- extra ffmpeg usage
- much more

ATTENTION! it is not necessary to write it by hand (although it is possible) - it is written by mpd itself. When we need to save it (for further use after reboots), we do so
cp /tmp/mpd_state /opt/mpd_state_1
save changes on the spi or sd flash drive
save_changes
now the desired state will survive reboots
