Some notes: * Unless `atmosphere!enable_log_manager` is true, Nintendo's log manager will be used instead. * This prevents paying memory costs for LM when not enabling logging. * To facilitate this, Atmosphere's log manager has a different program id from Nintendo's. * `atmosphere!enable_htc` implies `atmosphere!enable_log_manager`. * LogManager logs to tma, and the SD card (if `lm!enable_sd_card_logging` is true, which it is by default). * Binary logs are saved to `lm!sd_card_log_output_directory`, which is `atmosphere/binlogs` by default.
