Json-Manifest Reader

## Brief feature description

Parallel to the Toml Config File Provider Reader a new Config File Provider using json as format shall be created.

## Detailed information

The new Config File Provider shall use tiny_json as library for parsing the config file. This library has a better liability when checking it with a fuzzer test than the toml lib currently used.

- [ ] Introduce new external library tiny_json
- [ ] Implement roudi_config_json_file_provider.hpp
