Wohlstand 5bd573478b Updated libADLMIDI to version 1.5.1
Changelog
 * Added an ability to disable the automatical arpeggio
 * Added an ability to set the count of loops (how many times to play the song)
 * Added an ability to disable/enable playing of selected MIDI channels
 * Fixed memory damages and crashes while playing XMI files
 * Added bank-specific MT32 defaults (to don't confuse XMI playback between different games, works for AIL and IBK only, and for WOPL if set at the header)
 * Added the chip channels allocation mode option
 * Fixed the playback of multi-song XMI files
 * Added an ability to switch the XMI song on the fly

ALSO (future updates)
 * Fixed the work on big endian processors
 * Fixed ARM64 build on some platforms
 * Improved support of the EA-MUS files (Thanks to [dashodanger](https://github.com/dashodanger))
 * Fixed crash on attempt to change the volume of a blank note
