Add support for additional file formats

[bric3]

I think supporting TOML, properties, XML, YAML would be really useful. Basically these file have two types of comments

• Prefixed by #
• XMLs are special as the comment as to be surrounded by <!-- / -->, but must happen after <?xml version="1.0" standalone="no"?>

I don't know about other file types, but leaving the ability to declare them might like licensesnip might help support them without too much work.

{
  "use_gitignore": true,
  "file_types": {
    "js,mjs,ts,cjs,jsx,tsx": {
      "before_line": "// "
    },
    "vue,html": {
      "before_block": "<!--",
      "before_line": "  ",
      "after_block": "-->"
    },
    "rs": {
      "before_line": "// "
    },
    "c": {
      "enable": false
    }
  }
}

The given file types are often used for configuration, right now I don't really see any interest in licensing configuration files?

If I can be given a more precise use case that'd be nice.

I think if configuration files are needed to make the software work, most licenses consider them as source code.

More over they are a few tools that work with configuration as code, in this case the configuration file is also considered source code. Typically CI pipelines.

And I think that if a project finds a solution to drive a software via such configuration file, this has to be protected by license.

I am not a lawyer, but big project tend to apply the notice header on such files as well.
