Upgrade libADLMIDI and libOPNMIDI

Added full-panning stereo, improvement of channel management, and many other things.

Also, I have implemented an ability to use custom WOPL (for libADLMIDI) and WOPN (for libOPNMIDI) banks from the same path as "soundfonts", but also, in the same environment, the "fm_banks" folder was added for WOPL/WOPN storing purposes.
To toggle usage of embedded or custom bank, I have added togglable booleans. When bank fails to be loaded, the default embedded bank is getting to be used as fallback.

ADLMIDI 1.4.0   2018-10-01
 * Implemented a full support for Portamento! (Thanks to [Jean Pierre Cimalando](https://github.com/jpcima) for a work!)
 * Added support for SysEx event handling! (Thanks to [Jean Pierre Cimalando](https://github.com/jpcima) for a work!)
 * Added support for GS way of custom drum channels (through SysEx events)
 * Ignore some NRPN events and lsb bank number when using GS standard (after catching of GS Reset SysEx call)
 * Added support for CC66-Sostenuto controller (Pedal hold of currently-pressed notes only while CC64 holds also all next notes)
 * Added support for CC67-SoftPedal controller (SoftPedal lowers the volume of notes played)
 * Fixed correctness of CMF files playing
 * Fixed unnecessary overuse of chip channels by blank notes
 * Added API to disable specific MIDI tracks or play one of MIDI tracks solo
 * Added support for more complex loop (loopStart=XX, loopEnd=0). Where XX - count of loops, or 0 - infinite. Nested loops are supported without of any limits.
 * Added working implementation of TMB's velocity offset
 * Added support for full-panning stereo option (Thanks to [Christopher Snowhill](https://github.com/kode54) for a work!)
 * Fixed inability to play high notes due physical tone frequency out of range on the OPL3 chip

OPNMIDI 1.4.0   2018-10-01
 * Implemented a full support for Portamento! (Thanks to [Jean Pierre Cimalando](https://github.com/jpcima) for a work!)
 * Added support for SysEx event handling! (Thanks to [Jean Pierre Cimalando](https://github.com/jpcima) for a work!)
 * Added support for GS way of custom drum channels (through SysEx events)
 * Ignore some NRPN events and lsb bank number when using GS standard (after catching of GS Reset SysEx call)
 * Added support for CC66-Sostenuto controller (Pedal hold of currently-pressed notes only while CC64 holds also all next notes)
 * Added support for CC67-SoftPedal controller (SoftPedal lowers the volume of notes played)
 * Resolved a trouble which sometimes makes a junk noise sound and unnecessary overuse of chip channels
 * Volume models support taken from libADLMIDI has been adapted to OPN2's chip speficis
 * Fixed inability to play high notes due physical tone frequency out of range on the OPN2 chip
 * Added support for full-panning stereo option

ADL&OPN Hotfix: re-calculated default banks
The fix on side of measurer of OPL3-BE and OPN2-BE where some instruments getting zero releasing time.
