Update libADLMIDI and libOPNMIDI

[Wohlstand]

Since the previous update that I did in 2018, I didn't care about releases for a while. So, It's time to update!

I'll also send a commit to the GZDoom because of dependent changes.

libADLMIDI Changelog

1.5.0 2020-09-28

• Drum note length expanding is now supported in real-time mode (Thanks to Jean Pierre Cimalando for a work!)
• Channels manager has been improved (Thanks to Jean Pierre Cimalando for a work!)
• Nuked OPL3 1.8 emulator got some optimizations ported from 1.7 where they are was applied previously (Thanks to Jean Pierre Cimalando for a work!)
• Reworked rhythm-mode percussions system, WOPL banks with rhythm-mode percussions
• Added Public Domain Opal OPL3 emulator made by Reality (a team who originally made the Reality Adlib Tracker) (Thanks to Jean Pierre Cimalando for a work!)
• Added LGPL licensed JavaOPL3 emulator made by Robson Cozendey in Java and later rewritten into C++ for GZDoom (Thanks to Jean Pierre Cimalando for a work!)
• Fully rewritten an embedded bank database format, embedded banks now supports a wider set (more than 127:127 instruments in one bank)
• Improved accuracy of the DMX volume model, include the buggy AM interpretation
• Improved accuracy of Apogee volume model, include the bug of AM instruments
• Improved accuracy of the Win9X volume model
• Removed C++ extras. C++-bounded instruments tester is useless since a real-time MIDI API can completely replace it
• Added AIL volume model
• Added Generic FM variant of Win9X volume model
• Fixed an incorrect work of CC-121 (See https://github.com/Wohlstand/libADLMIDI/issues/227 for details)
• Added HMI volume model (Thanks to Alexey Khokholov for help with research!)
• Added frequency models, assigned to every volume model: AIL, HMI, DMX, Apogee, 9X, and the Generic formula

libOPNMIDI Changelog

1.5.0 2020-09-28

• Drum note length expanding is now supported in real-time mode (Thanks to Jean Pierre Cimalando for a work!)
• Added support for OPNA chip with Neko Project II Kai YM2602 emulator usage (Thanks to Jean Pierre Cimalando for a work!)
• Added VGM file dumper which allows outputting OPN2 commands into VGM file. (A new MIDI to VGM tool is now created with basing on libOPNMIDI) (This thing wasn't added into GZDoom specific copy as it's useless: for a work it requires MIDI2VGM tool)
• Fixed an incorrect work of CC-121 (See https://github.com/Wohlstand/libADLMIDI/issues/227 for details)
• Internality has been refactored and improved

Damn, I forgot to include the workaround for MSVC at PMDWin emulator... it won't build because of missing unistd.h.
