Description
I'm using binary-c API. I need to read modules from arbitrary binaries and do some analysis on them, including analyzing their data sections.
I find BinaryenCopyMemorySegmentData(BinaryenModuleRef module, const char* segmentName, char* buffer), but this requires segmentName, which I can't determine for an arbitrary binary. I don't find any API like BinaryenGetMemorySegmentByIndex or BinaryenMemorySegmentGetName just like those for functions.

Research direction
Start with the binary-C API entry point BinaryenCopyMemorySegmentData and compare it with the existing function traversal and lookup APIs mentioned in the issue. Determine whether memory segments can be enumerated and identified for arbitrary binaries, then document the supported access path or define the missing API behavior.
