Should this be able to work implicitly, same as a debugger? (presumably there's some logic (both as a concept, but concretely as code in lldb or somewhere similar) that knows how to find dsyms when they're in some standard layout (presumably `binary_name` has `binary_name.dsym` next to it, maybe some search path too)) Not sure if the debugger even has a way to explicitly tell it where a dsym is - and if it doesn't, probably not suitable to add such a thing to other debug info-consuming tools?
