* add conf.d directory for config overrides * refactor llarp::Config * add explicit constructor with datadir as parameter * have all config files be passed as std::optional * make Config::LoadDefault private and use std::optional in Config::Load to remove ambiguity * update rest of codebase to reflect above changes * fix pybind * rename bootstrap config skipBootstrap to seednode as it's more descriptive * make seednode configurable * make pybind layer compile * make pybind layer run
