Error using BinExport with Ghidra 11.3.2

[spcnvdr]

When trying to use BinExport with Ghidra 11.3.2 I get an exception like below. This occurs when trying to export a program after installing the extension. The BinExport extension continues to work with Ghidra 11.3.1, so I am unsure what changed with the new version of Ghidra to cause this.

class com.google.security.zynamics.BinExport$BinExport2 tried to access method 'com.google.protobuf.LazyStringArrayList com.google.protobuf.LazyStringArrayList.emptyList()' (com.google.security.zynamics.BinExport$BinExport2 and com.google.protobuf.LazyStringArrayList are in unnamed module of loader ghidra.GhidraClassLoader @483bf400)

Broken for me too:

I tested and successfully reproduced the behavior. Building with protobuf 3.21.12 and #155 fixed it. The PR solves the compile-time errors.

#155 has been merged.
