docs: Parses a file into a Config instance. Does not call
  {@link Config#resolve} or merge the file with any other
  configuration; this method parses a single file and does
  nothing else. It does process "include" statements in the
  parsed file, and may end up doing other IO due to those
  statements.
  
  @param file
  the file to parse
  @param options
  parse options to control how the file is interpreted
  @return the parsed configuration
  @throws ConfigException on IO or parse errors
