Support a simpler config file format

[x4e-jonas]

JSON is hard to read and write for humans. E.g. you can't just diff/merge lines of config and it does not support comments.

I'd suggest TOML since it's a very simple standardized format and Java implementations are already available. Other candidates are YAML, INI or HCL like formats.

While the JSON standard does not include comments, many parsers, including the one cineast uses, support C-style comments, so you can use comments if you want. TOML could potentially be an alternative if one wanted. I'm not a bit fan of INI and YAML, as they are somewhat limited and/or cumbersome. There's also HOCON which, being a superset of JSON would have the advantage that configurations would even stay backwards compatible.

@x4e-jonas I would like to help you with this issue, the config file is extraction_config.json ?
