feat(add compact arrays): we can now have nice one line syntax for arrays

[hube12]

This refer to my recent issue #298 where I mention I would love a compact array definition,
This PR allow to do so by using the with_compact_arrays(true), the default is false ofc.

assert_eq!(
        to_string_pretty(&&[(), (), ()][..], PrettyConfig::new().with_new_line("\n".to_string()).with_compact_arrays(true)).unwrap(),
        "[(),(),()]"
    );

I think it has good as it can gets for this specific use case, there is still the issue of structs inside array so maybe compact_arrays could be extended to compact_array_if_level_below(level) so only leaf structure are compact but nested ones aren't

Either that, or define a char limit for "compact arrays" (could do the same with structs / maps, too, I guess)

Here are 2 things that we'll need to follow-up with:

1. same PR as this for the master branch
2. add a commit to this PR with a patch version bump and a short CHANGELOG entry
