add config command with create/list/show with --user/--sys, add global param --debug/--verbose

- set default _debug output to false
  - add global param --debug/--verbose to enable _debug output
- changed user config store path
  - on windows, it will be "~/AppData/Roaming"
  - on linux, it still is "~/.config"
- added supported to system global config
  - which means "C:/ProgramData" on Windows and "/etc" on linux
  - the system global config can be override by user config
- add config command
  - with param --user/--sys, which can control config command do on which config field. the default is user.
  - with subcommand create, it can create sekai-scores config dir and config file. it follows config field.
  - with subcommand list/show, it can show the config loaded. it shows all of the config will be load. so, it do not follow config field setting.
  - without subcommand, it will output the config file path.
