Is your feature request related to a problem or challenge? Please describe what you are trying to do.
In working with the library, we have hit cases where we have an existing set of WriterProperties that we want to use as a template for a set of files. But we want to modify some properties on a file-by-file basis. Unfortunately, there is no easy way to do this since the members are private.

Describe the solution you'd like
We propose adding an into_builder method to go from WriterProperties to WriterProptertiesBuilder.

Describe alternatives you've considered
A WriterPropertiesBuilder From WriterProperties could also make sense. But, into_builder is more explicit and is commonly used in the library.
