Move EmuNAND

This is an add-on section for moving the contents of a previous EmuNAND to your new SysNAND CFW, then removing the old EmuNAND partition. Note that the terms EmuNAND and RedNAND refer to slightly different implementations of the same concept.

You MUST have already installed arm9loaderhax + Luma3DS to use this.
