my phone is aarch64 so this is a small stumbling block
   websearching found this article on reverse engineering go binaries
   using
   ghidra: [1]https://cujo.com/reverse-engineering-go-binaries-with-ghidra
   /
   dunno if it's any good, but it's fun to try to install ghidra on my
   phone!
   maybe check for strings first
