[Bug] Crashes with big soundfonts

[kurenai-11]

Hey. Recently found this lib, works great, but I noticed that it crashes when you try to use big (hundreds of mb) .sf2 files. Tried to load 379mb one, crashed, but, for reference, other 214mb one works for me.

Device: Redmi Note 12 OS: Android 13 Crash log:

Performing hot restart...

It may be fixed in the new version, but there will be problems until the Android method changes. Because the desktop Java library is used on the Android platform. Ios and Macos have their own libraries for this.
