feat/refacto: improve configurations

- You should now get the configs through functions
- Configs for languages are now inside a local object called parsers
- You can get the parser installation configurations with `get_parser_configs`
- A new object has been initialized inside configs to specify module config (called config).
- Provide functions to enable/disable a module on one buffer
- Provide functions to enable/disable a module on all buffers, and if filetype is
  specified, for specific filetype
- Provide function to determine if module is activated for a specified filetype
