instrument not detected coz method getSoundfontInstrumentName is wrong

[burmistrov-alexander]

Hi!

this method doesnt replace round brackets

private getSoundfontInstrumentName(midiName: string): string {
return midiName.toLowerCase().replace(/\s+/g, "_");
}

midiinstruments:
...
[24, "Acoustic Guitar (nylon)"],
[25, "Acoustic Guitar (steel)"],
[26, "Electric Guitar (jazz)"],
[27, "Electric Guitar (clean)"],
[28, "Electric Guitar (muted)"],
...
so, after calling getSoundfontInstrumentName() this names we got "acoustic_guitar_(nylon)" but it should be "acoustic_guitar_nylon", because file musyngkiteInstruments.ts include this name.
