Wohlstand faa997b986 Updated libOPNMIDI to 1.5.1
Changelog:
 * Added an ability to disable the automatical arpeggio
 * Updated the GENS chip emulator from the 2.10 into GS/II (thanks to @freq-mod for the help)
 * Added an ability to set number of loops
 * Added an ability to disable/enable playing of selected MIDI channels
 * Fixed memory damages and crashes while playing XMI files
 * 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

And also:
 * 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
