local dump_syms integration?

minidump-processor has support for fetching binaries from a symbol server and running dump_syms on them, but in principle minidump-debugger could go one step further and support you pointing it at a build dir/exe and running dump_syms on it.

This would probably be the most useful workflow for random users.

Bonus points if it can detect "what you did wrong" with your debug flags and recommend improvements?
