zstd compressed debug sections are not parsed

[trumank]

Version and Platform (required):

• Binary Ninja Version: 4.2.6168-dev Personal, cb0f14d8
• OS: arch
• OS Version: unknown
• CPU Architecture: x86_64

Bug Description:
Binary Ninja does not read/parse debug sections compressed with zstd.

Steps To Reproduce:

#include <iostream>
#include <ostream>
#include <string>

struct Test {
  std::string msg;
};

int main() {
  Test t{.msg = "Hello, World!"};
  std::cout << t.msg << std::endl;
  return 0;
}

g++ hello.cpp -g -fuse-ld=mold -Wl,--compress-debug-sections=zstd -o hello

Open hello in Binary Ninja and observe there is no struct named Test defined. Change the compression type to zlib or remove entirely and it will appear.

Additional Information:
I ran into this with my own tools using the object crate, perhaps related: gimli-rs/object#730
