Use derive-builder in the runner crate

[saulecabrera]

The javy-runner contains a builder that reconciles all the CLI options and therefore it has grown (and will continue to grow) to contain a wide range of fields. As per @surma's suggestion, we could consider using the derive-builder crate to reduce some of the boilerplate.

Just discovered typed-builder. Both wildly popular. Worth looking and comparing.
