Option to keep vertical spacing

Often I use vertical space to make it a little easier on the eyes. Possible to add an option to support this?

This is a limitation of by the underlying library that provides formatting. If there is a library that handles this I would consider switching.

If no existing suitable library can be found and someone wants to take this on, my recommendation would be to start from the parsed AST from yaml-ast-parser (already used by this project) and write new formatted output from that. There you could include options for preserving whitespace in your implementation. If doing this, you may want to consider mulesoft-labs/yaml-ast-parser#1 as your implementation could also resolve that issue as well (and the code referenced there may be a starting point).
