Add option to HOCON loader to put spacing between statements

[spektrsoyuz]

Currently, the HoconConfigurationLoader does not support an option to save a configuration node with a white space character between statements.

Example of the loader I am using:

private HoconConfigurationLoader createLoader(final Path file) {
        return HoconConfigurationLoader.builder()
                .prettyPrinting(true)
                .defaultOptions(opts -> opts.shouldCopyDefaults(true))
                .path(file)
                .build();
}

Desired outcome:
prefix = "my prefix"

Actual outcome:
prefix="my prefix"

Having a way to enable/customize this would allow for better formatting for HOCON files.
